In order to solve it you have to get x by itself.
1. Simplify. 1/4 + 1/2 + x is also the same as 3/4 + x. So you have 3/4 + x = -3/4.
2. Then you subtract 3/4 on both sides to get x by itself. x = -3/4 - 3/4
3. Simplify. x = -1 1/2 or -1.5 depending on whether you need the answer in a fraction or a decimal.
