62(3x3) =18
66x6=18
12x=6=18=24
12x=24
x=2
check this problem is it right.

no
62(3x3) =18
66x+6=18
6 x + 12 = 18
6 x =  30
x = 5
check
6  2(153) = 18???
6  24 = 18
18 = 18 yes, check 
62(3x3) =18
66x6=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.
62(3x3) =18
6  6x + 6 = 18
12 + 18 = 6x
5 = x
Check it out by substituting 5 for x in your original problem.
