-3x - 8 = -29

1 answer

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

For the first equation, when we substitute -7 for x, we get:

5(-7) + 11 = -24
-35 + 11 = -24
-24 = -24

The equation is satisfied when x = -7.

For the second equation, when we substitute -7 for x, we get:

4(-7) - 23 = 5
-28 - 23 = 5
-51 = 5

The equation is not satisfied when x = -7.

For the third equation, when we substitute -7 for x, we get:

-(-7) + 3 = -4
7 + 3 = -4
10 = -4

The equation is not satisfied when x = -7.

For the fourth equation, when we substitute -7 for x, we get:

-3(-7) - 8 = -29
21 - 8 = -29
13 = -29

The equation is not satisfied when x = -7.

Therefore, the first equation, 5x + 11 = -24, has a solution of -7.
