You can put this solution on YOUR website!
One way to look at this is to try several values. In general we start with the assumption that we use positive integers.
If x = 3, we get
5%5E3+-+4%5E3+=+8%5E2+-+3
125 - 64 = 64 - 3
61 = 61.
As a footnote, the only answer is 3.
Sorry I don't have a neat algebraic solution for you.
