This is a basic algebra problem. In order to solve this you have realize what kind of equation this is. This equation is asking for both sides to be equal. In order to do that you have to subtract 7 from 15 to find what x equals.
15=x+7
-7 -7
15-7=x+7-7
8=x
This means that in this equation, x equals 8. Plug it back in to check.
15=8+7
15=15. This works perfectly!!!
