    It has two solutions, either \(3x-3=12 \implies 3x=15 \implies x=5 \) or \(3x-3=-12 \implies 3x=-9 \implies x=-3\).

    Whats the trial and error method?

    You shouldn't use trial and error. The solution is to set 3x-3 equal to 12, and then set it equal to -12. Because |12|=|-12|=12.

    We can! But it's not very easy to find the right answer, especially when the expression is much complicated.
