6-2(3x-3) =-18

6-6x+6=-18

-6 x + 12 = -18

-6 x = - 30

x = 5

check

6 - 2(15-3) = -18???

6 - 24 = -18

-18 = -18 yes, check

6-6x-6=-18

12x=-6=18=24

12x=24

x=2

Your first step is incorrect. When you multiply two negatives, the answer is a positive.**6 - 6x + 6 = -18**

I don't know where you got 12x.

**6-2(3x-3) =-18**

6 - 6x + 6 = -18

12 + 18 = 6x

5 = x

Check it out by substituting 5 for x in your original problem.
