Well I don't know !
Let's work it out together:

                                       3(x - 2) = -3x + 42

Eliminate parentheses:    3x - 6  =  -3x + 42

Add  6  to each side:        3x        =  -3x + 48

Add  3x  to each side:      6x        =            48

Divide each side by  6 :     x        =              8
