y=5x+7

3y−15x=18


x−2y=6

3x−6y=18


y = 3x + 6
y=−13x−4
y=23x−1
y=23x−2

Answer 2

Match the system of equations to the number of solutions it has.

y=5x+7 and 3y−15x=18

x−2y=6 and 3x−6y=18

y = 3x + 6 and y=−13x−4

y=23x−1 and y=23x−2

Answer 5

The Woodson and Baker families went to the Burger Shack for dinner. The Woodsons bought 3 burger meals and 4 hot dog meals for $48. The Bakers bought 6 burger meals and 2 hot dog meals for $60. How much does each meal cost? Show your work.

​If x represents the cost of burger meals, then y represents Response area.

The system of linear equations would look like Response area.

How much does a burger meal cost? Response area

How much does a hot dog meal cost?

Answer 12

1. Isolate one variable in one equation (e.g. solve one equation for x or y).
2. Substitute the expression found in step 1 into the other equation, replacing that variable.
3. Solve the resulting equation for the remaining variable (it should only have one variable).
4. Substitute the value found in step 3 back into either equation to find the value of the other variable.
5. Check the solution by plugging in the values found for both variables into both original equations. If both equations are true, then the solution is correct.

Answer 13

Sure!

1. Isolate one variable in one equation. Let's isolate y in the first equation by adding 7x to both sides:

-7x - 2y = -13
-2y = -6x - 13
y = 3x + 6.

2. Substitute the expression found in step 1 into the other equation, replacing that variable:

-13x - 2(3x + 6) = 11.

3. Solve the resulting equation for the remaining variable (it should only have one variable):

-13x - 6x - 12 = 11
-19x = 23
x = -23/19.

4. Substitute the value found in step 3 back into either equation to find the value of the other variable. Let's use the first equation:

-7(-23/19) - 2y = -13
161/19 - 2y = -13
2y = 161/19 + 13
y = 434/38 = 217/19.

5. Check the solution by plugging in the values found for both variables into both original equations. If both equations are true, then the solution is correct.

Checking the first equation:

-7(-23/19) - 2(217/19) = -13
-161/19 - 434/19 = -13
-595/19 = -13

The equation is true.

Checking the second equation:

-13(-23/19) - 2(217/19) = 11
299/19 + 434/19 = 11
733/19 = 11

The equation is also true.

Therefore, the solution is x = -23/19 and y = 217/19.

Answer 14

If x represents the cost of burger meals, then y represents the cost of hot dog meals.

The system of linear equations would look like:

3x + 4y = 48
6x + 2y = 60

We can use substitution to solve for one of the variables. Let's solve for y by isolating it in the first equation:

3x + 4y = 48
4y = -3x + 48
y = (-3/4)x + 12

Now we can substitute this expression for y into the second equation and solve for x:

6x + 2y = 60
6x + 2((-3/4)x + 12) = 60
6x - (3/2)x + 24 = 60
(9/2)x = 36
x = 8

So a burger meal costs $8. Now we can use the first equation to solve for y:

3x + 4y = 48
3(8) + 4y = 48
24 + 4y = 48
4y = 24
y = 6

Therefore, a hot dog meal costs $6.

Answer 15

The solution to the system of equations is (x = 1, y = 2).

Answer 16

There is one unique solution to the system of equations, which is (x = 1, y = 2).

Answer 17

(0,-2) is not a solution to the system of equations 8x-2y=-4 and 4x-y=-2. You can check this by plugging in those values for x and y and seeing if both equations are true:

8(0) - 2(-2) = 4, which is not equal to -4. Therefore, (0,-2) is not a solution to the system.
