How many solutions does the system of equations have? 6x+2y=−18 3x+y=24 (1 point)

Answer 18

To solve the system of equations, we will use the substitution method.

Given:

x = 6y - 3 ...(Equation 1)
2x + 7y = 13 ...(Equation 2)

From Equation 1, we have:

x + 3 = 6y ...(Equation 3)

We will substitute Equation 3 into Equation 2:

2(x + 3) + 7y = 13
2x + 6 + 7y = 13
2x + 7y = 7 ...(Equation 4)

Now, we have the following system of equations:

x = 6y - 3 ...(Equation 1)
2x + 7y = 7 ...(Equation 4)

We can solve this system of equations by eliminating x. Multiply Equation 1 by 2:

2x = 12y - 6

Substitute this value for 2x in Equation 4:

12y - 6 + 7y = 7
19y - 6 = 7
19y = 13
y = 13/19

Substitute this value for y in Equation 1:

x = 6 (13/19) - 3
x = 78/19 - 57/19
x = 21/19

Therefore, the solution to the system of equations is x = 21/19 and y = 13/19.

Answer 19

The solution to the system of equations is (x, y) = (21/19, 13/19).

Answer 20

The solution to the system of equations is (x, y) = (3, 2/3).

Answer 21

Apologies for the mistake. Let's re-solve the system of equations:

Given:

x = 6y - 3 ...(Equation 1)
2x + 7y = 13 ...(Equation 2)

We will substitute the value of x from Equation 1 into Equation 2:

2(6y - 3) + 7y = 13
12y - 6 + 7y = 13
19y - 6 = 13
19y = 19
y = 1

Now, substitute the value of y = 1 back into Equation 1:

x = 6(1) - 3
x = 6 - 3
x = 3

Therefore, the solution to the system of equations is (x, y) = (3, 1).

Answer 22

To solve the system of equations, we will use the substitution method.

Given:
8x - 3y = -22 ...(Equation 1)
y = 10 + 4x ...(Equation 2)

We will substitute the value of y from Equation 2 into Equation 1:

8x - 3(10 + 4x) = -22
8x - 30 - 12x = -22

Combine like terms:
-4x - 30 = -22

Add 30 to both sides:
-4x = 8

Divide both sides by -4:
x = -2

Now, substitute the value of x = -2 back into Equation 2 to find y:

y = 10 + 4(-2)
y = 10 - 8
y = 2

Therefore, the solution to the system of equations is (x, y) = (-2, 2).

Answer 23

To solve the system of equations, we will use the elimination method.

Given:
5x + 2y = 14 ...(Equation 1)
x - 6y = 22 ...(Equation 2)

Multiply Equation 2 by 5 to match the coefficients of x:

5(x - 6y) = 5(22)
5x - 30y = 110

Now, we have the following system of equations:

5x + 2y = 14 ...(Equation 1)
5x - 30y = 110 ...(Equation 3)

Next, subtract Equation 1 from Equation 3 to eliminate x:

(5x - 30y) - (5x + 2y) = 110 - 14
5x - 30y - 5x - 2y = 96
-32y = 96

Divide both sides by -32:
y = 96/-32
y = -3

Now substitute the value of y = -3 into Equation 1 to solve for x:

5x + 2(-3) = 14
5x - 6 = 14
5x = 20
x = 20/5
x = 4

Therefore, the solution to the system of equations is (x, y) = (4, -3).

Answer 24

To solve the system of equations, we will use the substitution method.

Given:
-9 + y = 12 ...(Equation 1)
2x + 4y = -28 ...(Equation 2)

From Equation 1, we can isolate y:
y = 12 + 9
y = 21

Now, substitute the value of y = 21 into Equation 2:

2x + 4(21) = -28
2x + 84 = -28
2x = -28 - 84
2x = -112
x = -112/2
x = -56

Therefore, the solution to the system of equations is (x, y) = (-56, 21).

Answer 25

Apologies for the mistake. Let's re-solve the system of equations:

Given:
-9 + y = 12 ...(Equation 1)
2x + 4y = -28 ...(Equation 2)

From Equation 1, we can isolate y:
y = 12 - 9
y = 3

Now, substitute the value of y = 3 into Equation 2:

2x + 4(3) = -28
2x + 12 = -28
2x = -28 - 12
2x = -40
x = -40/2
x = -20

Therefore, the solution to the system of equations is (x, y) = (-20, 3).

Answer 26

Apologies for the mistake. Let's double-check the solution:

Given:
-9 + y = 12 ...(Equation 1)
2x + 4y = -28 ...(Equation 2)

From Equation 1, we can isolate y:
y = 12 - (-9)
y = 12 + 9
y = 21

Now, substitute the value of y = 21 into Equation 2:

2x + 4(21) = -28
2x + 84 = -28
2x = -28 - 84
2x = -112
x = -112/2
x = -56

Therefore, the correct solution to the system of equations is (x, y) = (-56, 21).

Answer 27

To solve the system of equations, we will use the elimination method.

Given:
6x + 2y = -18 ...(Equation 1)
3x + y = 24 ...(Equation 2)

Multiply Equation 2 by 2 to match the coefficients of y:

2(3x + y) = 2(24)
6x + 2y = 48

Now, we have the following system of equations:

6x + 2y = -18 ...(Equation 1)
6x + 2y = 48 ...(Equation 3)

Next, subtract Equation 1 from Equation 3 to eliminate x and y:

(6x + 2y) - (6x + 2y) = 48 - (-18)
0 = 48 + 18
0 = 66

Since 0 does not equal 66, the system of equations is inconsistent and has no solution.

Therefore, this system of equations has no solution.

Answer 28

To solve the system of equations using substitution, we will substitute the value of y from the first equation into the second equation:

Given:
y = 2 + 3x ...(Equation 1)
4x - 3y = -16 ...(Equation 2)

Substitute y = 2 + 3x into Equation 2:
4x - 3(2 + 3x) = -16

Distribute the -3:
4x - 6 - 9x = -16

Combine like terms:
-5x - 6 = -16

Add 6 to both sides:
-5x = -10

Divide both sides by -5:
x = 2

Now substitute the value of x = 2 into Equation 1 to find y:

y = 2 + 3(2)
y = 2 + 6
y = 8

Therefore, the solution to the system of equations is (x, y) = (2, 8).

Answer 29

To solve the system of equations, we can substitute the value of x from the second equation into the first equation:

Given:
2x + 6y = -18 ...(Equation 1)
x = 5y - 1 ...(Equation 2)

Substitute x = 5y - 1 into Equation 1:
2(5y - 1) + 6y = -18
10y - 2 + 6y = -18
16y - 2 = -18

Add 2 to both sides:
16y = -16

Divide both sides by 16:
y = -1

Now substitute the value of y = -1 back into Equation 2 to find x:

x = 5(-1) - 1
x = -5 - 1
x = -6

Therefore, the solution to the system of equations is (x, y) = (-6, -1).

Answer 30

To solve the system of equations:

3x + y = 2 ...(Equation 1)
7x - 4y = 30 ...(Equation 2)

We will use the substitution method.

From Equation 1, we can isolate y:
y = 2 - 3x

Now substitute the value of y from Equation 1 into Equation 2:

7x - 4(2 - 3x) = 30
7x - 8 + 12x = 30
19x - 8 = 30
19x = 38
x = 38/19
x = 2

Now substitute the value of x = 2 back into Equation 1 to find y:

3(2) + y = 2
6 + y = 2
y = 2 - 6
y = -4

Therefore, the solution to the system of equations is (x, y) = (2, -4).

Answer 31

To solve the system of equations:

-4x + 6y = 38 ...(Equation 1)
x - 5y = -20 ...(Equation 2)

We will use the elimination method to eliminate x.

Multiply Equation 2 by 4 to make the coefficients of x in both equations equal:
4(x - 5y) = 4(-20)
4x - 20y = -80

Now, we have the system of equations:

-4x + 6y = 38 ...(Equation 1)
4x - 20y = -80 ...(Equation 3)

Adding Equation 1 and Equation 3, we can eliminate x:

(-4x + 6y) + (4x - 20y) = 38 + (-80)
-14y = -42
y = -42 / -14
y = 3

Substitute the value of y = 3 into Equation 2 to find x:

x - 5(3) = -20
x - 15 = -20
x = -20 + 15
x = -5

Therefore, the solution to the system of equations is (x, y) = (-5, 3).

Answer 32

To solve the system of equations:

-5x + y = -18 ...(Equation 1)
10x - 2y = 36 ...(Equation 2)

We will use the elimination method to eliminate y. Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(-5x + y) = 2(-18)
-10x + 2y = -36

Now, we have the system of equations:

-5x + y = -18 ...(Equation 1)
-10x + 2y = -36 ...(Equation 3)

Adding Equation 1 and Equation 3, we can eliminate y:

(-5x + y) + (-10x + 2y) = -18 + (-36)
-15x = -54
x = -54 / -15
x = 3.6

Now substitute the value of x = 3.6 into Equation 1 to find y:

-5(3.6) + y = -18
-18 + y = -18
y = -18 + 18
y = 0

Therefore, the solution to the system of equations is (x, y) = (3.6, 0).

Answer 33

To determine the number of solutions for the system of equations:

-5x + y = -18 ...(Equation 1)
10x - 2y = 36 ...(Equation 2)

We can rewrite Equation 1 as y = 5x - 18 by moving the -5x term to the other side.

The slope of Equation 1 is 5, and the slope of Equation 2 is 10/2 = 5 as well. This means that the two lines are parallel and will never intersect.

Since the lines are parallel and will never intersect, the system of equations has no common solution. Therefore, the system has no solutions.

Answer 34

You're welcome! If you have any more questions, feel free to ask.

Answer 35

To determine the number of solutions for the system of equations:

6x + 2y = -18 ...(Equation 1)
3x + y = 24 ...(Equation 2)

We can rewrite Equation 1 as y = -3x - 9 by dividing both sides by 2.

The slope of Equation 1 is -3, and the slope of Equation 2 is -3 as well. Additionally, the y-intercept of Equation 1 is -9, and the y-intercept of Equation 2 is 24.

Since the slopes are the same and the y-intercepts are different, the two lines are parallel and will never intersect.

Since the lines are parallel and will never intersect, the system of equations has no common solution. Therefore, the system has no solutions.
