Here goes: Where X + 13% of X = 200. Solve X Note - The percentage and the number 200 are arbitrary. Either of these could be infinite.

Well, the number 200 can't be infinite, but I know what you mean. In cases where either the percent or the given constant is infinite, there is no solution for X.
