To solve the equation 12 = |-3 + 3x |, we need to consider two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: -3 + 3x is positive

If -3 + 3x is positive, then the equation becomes -3 + 3x = 12.

Solve for x:

-3 + 3x = 12

-3 + 3x + 3 = 12 + 3

3x = 15

3x/3 = 15/3

x = 5
