    Finding explicit solutions is absolutely vile. However, you get a necessary condition on the solution (that is, the condition that x^4+y^4 = c) by multiplying the two equations together. I don't know if that's truly the solution, though (it's a necessary condition, but I don't see why it's a sufficient condition).
