Answer:

x = -4

Explanation:

We are given the expression -7x - 4 = -8x + 8 and are asked to solve for x. To do so, we need to isolate x entirely. Start by getting only one side have the variable x, add 7x to both sides:

-7x - 4 = -8x + 8

-4 = -x + 8

Now we need to get on the only side alone, subtract by both sides:

-4 = -x + 8

4 = -x

-x = 4

Now we can't have a negative x, so we need to divide both sides by a negative 1:

-x = 4

x = -4
