real=True, or even positive=True can help SymPy to simplify things sometimes (like sqrt(x**2) -> abs(x) for x real or x for x positive).
SymPy also has limited algorithms implemented for solving nonlinear systems of equations, so it's quite possible that if there is a solution, SymPy won't be able to find it.
