Answer 6

The equations are as follows:
1) x + 25 = 2
2) x - 6 = 16
3) x + 19 = -5
4) x - 7 = 28

To find the solution with the lowest value, we need to solve each equation and compare the values of x.

1) x + 25 = 2
Subtract 25 from both sides:
x = 2 - 25
x = -23

2) x - 6 = 16
Add 6 to both sides:
x = 16 + 6
x = 22

3) x + 19 = -5
Subtract 19 from both sides:
x = -5 - 19
x = -24

4) x - 7 = 28
Add 7 to both sides:
x = 28 + 7
x = 35

Comparing the values of x from each equation, we can see that the equation with the lowest solution value is:
x = -24 (from equation 3: x + 19 = -5).

Answer 7

To find the equation that has a different value of x than the others, we need to solve each equation and compare the values of x.

1) x - 7/8 = -3/2
To isolate x, we add 7/8 to both sides:
x = -3/2 + 7/8

2) x + 9/8 = 7/4
To isolate x, we subtract 9/8 from both sides:
x = 7/4 - 9/8

3) x - 0.025 = 0.6
To isolate x, we add 0.025 to both sides:
x = 0.6 + 0.025

4) x + 0.0875 = 1.5
To isolate x, we subtract 0.0875 from both sides:
x = 1.5 - 0.0875

Now we can compare the values of x from each equation:

1) x = -3/2 + 7/8
2) x = 7/4 - 9/8
3) x = 0.6 + 0.025
4) x = 1.5 - 0.0875

By comparing the values of x, we can see that the equation with a different value of x is:
x = 0.6 + 0.025 (from equation 3: x - 0.025 = 0.6).

Answer 8

To solve for x in the equation x/-5 = 2, we can multiply both sides by -5:

(x/-5)(-5) = 2(-5)

Simplifying, we get:

x = -10

Therefore, the value of x is -10.

Answer 9

To determine which pair of equations has exactly the same solution, we need to solve each pair of equations separately.

1) -3/4x + 5/2 and 5/2x = 3/4
Simplifying the first equation, we have:
-3/4x + 5/2 = 0

To solve for x, we can subtract 5/2 from both sides:
-3/4x = -5/2

Now, multiply both sides by -4/3 to isolate x:
x = (-5/2) * (-4/3)
x = 10/3

For the second equation, we have:
5/2x = 3/4

We can multiply both sides by 2/5:
x = (3/4) * (2/5)
x = 6/20
x = 3/10

The solutions for the first equation and the second equation are x = 10/3 and x = 3/10, respectively. These solutions are not the same.

2) x/3.2 = 1.8 and 1.8 = 3.2
For the first equation, we have:
x/3.2 = 1.8

To solve for x, we can multiply both sides by 3.2:
x = 3.2 * 1.8
x = 5.76

For the second equation, we have:
1.8 = 3.2

This equation states that 1.8 is equal to 3.2. However, this is not true, so this equation does not have a solution.

3) 3/8x = 1 and 1/3x = 1/8
For the first equation, we have:
3/8x = 1

To solve for x, we can multiply both sides by 8/3:
x = (1) * (8/3)
x = 8/3

For the second equation, we have:
1/3x = 1/8

To solve for x, we can multiply both sides by 8/1:
x = (1/8) * (8/1)
x = 1

The solutions for the first equation and the second equation are x = 8/3 and x = 1, respectively. These solutions are not the same.

4) -3.2 = .64 and x/4 = -.05
For the first equation, we have:
-3.2 = .64

This equation states that -3.2 is equal to 0.64. However, this is not true, so this equation does not have a solution.

For the second equation, we have:
x/4 = -0.05

To solve for x, we can multiply both sides by 4:
x = -0.05 * 4
x = -0.2

The solutions for the first equation and the second equation are not the same.

Therefore, none of the pairs of equations have the same solution.

Answer 10

To determine which equation has a solution of -7, we can substitute -7 for x in each equation and see which one satisfies the equation.

1) 4x - 23 = 5
Substituting -7 for x:
4(-7) - 23 = 5
-28 - 23 = 5
-51 = 5
This equation is not true when x = -7.

2) -3x - 8 = -29
Substituting -7 for x:
-3(-7) - 8 = -29
21 - 8 = -29
13 = -29
This equation is not true when x = -7.

3) 5x + 11 = -24
Substituting -7 for x:
5(-7) + 11 = -24
-35 + 11 = -24
-24 = -24
This equation is true when x = -7.

4) -x + 3 = -4
Substituting -7 for x:
-(-7) + 3 = -4
7 + 3 = -4
10 = -4
This equation is not true when x = -7.

Out of the given equations, only the equation 5x + 11 = -24 has a solution of x = -7.

Answer 11

To determine which equation has a solution different from the rest, we need to solve each equation and compare the values of x.

1) 3/4x + 5 = -1/4
To isolate x, we subtract 5 from both sides:
3/4x = -1/4 - 5

2) -1/7x - 3/4 = 1/4
To isolate x, we add 3/4 to both sides:
-1/7x = 1/4 + 3/4

3) -0.35x - 0.52 = 1.93
To isolate x, we add 0.52 to both sides:
-0.35x = 1.93 + 0.52

4) 1/2x - 3 = 1/2
To isolate x, we add 3 to both sides:
1/2x = 1/2 + 3

By comparing the equations, we can see that the equation with a different solution is:
-0.35x - 0.52 = 1.93 (from equation 3: -0.35x - 0.52 = 1.93).

To find the specific value of x, let's solve the equation:
-0.35x - 0.52 = 1.93

Adding 0.52 to both sides:
-0.35x = 2.45

Dividing both sides by -0.35:
x = 2.45 / -0.35

Calculating the division:
x ≈ -7

Therefore, the equation -0.35x - 0.52 = 1.93 has a different solution than the rest, with x ≈ -7.
