Is A dense or sparse? Solving a linear system of 100 equations and 100 unknowns is not something that symbolic solvers are generally good at. For example, I don't think you aren't guaranteed to have good numerical conditioning for the expressions for x. Is it required that you have symbolic expressions for the values of x? If not then you should probably look to numerical solvers like those available in SciPy.
