Oops the problem cannot be solved the way you have written it. You must be missing a term or there is a typo in your math book.

x-(-2x -2) + 3 = 3x + 9
x + 2x + 2 + 3 = 3x + 9
3x + 5 = 3x + 9
5 = 9 Since this statement is not true, your equation is not a valid one.

This is not true.
The equation has no solution.
