If 2x+3=0, like I'm assuming it does, then x=-1.5
Steps
1: You start by getting rid of any addition or subtraction by doing the opposite. To get rid of addition, do subtraction and vice versa. So 2x=-3
2: Then you get rid of multiplication by using division and vice versa to get rid of division. so x=-3 or -1.5

However, if you were looking for a different answer, you may want to try put that the problem equals 2 or 5 or 17 or something like that at the end of the problem.
