-1 is the answer.
(Distribute 3 through the parenthesis and then distribute-2 through the parenthesis)
3x+3 = +2x+2-4
(Move the variable to the left side and change its sign and then move the constant to the right side and change its sign)
3x+2x = -2-3
(Collect the like and then calculate the sum or difference)
5x = -1
(Divide both sides of the equation by 5)
x = -1
