Answer: x = -8

Explanation:

We have -81 = 3(3x-3)

Starting with the parenthesis, we have 3(3x-3). Multiply 3 by (3x-3) and we get 9x-9.

Putting it together, we have -81=9x-9. Now we need to isolate the numbers to one side and x on the other to find what x is.

-81 = 9x -9

+9 +9

-72 = 9x

-72 = 9x

9 9

-8 = x
