Cramer's method is useful for instructive purposes, and also for theory, but practically, it is highly inefficient. The method used by SymPy is Gaussian elimination, which is the most direct way to solve a system of linear equations.
Of course, if you want to use SymPy to use Cramer's method, that is possible. I'm not sure what the best method to get the matrices with columns replaced is. Perhaps we should add some method like col_replace (and row_replace) to Matrix, which would make this easier.
