Thanks for that link.

And as you already suggested: Cramer's Rule is not very efficient in general and should probably be avoided for numerical calculations, especially when the dimension goes up.

And I am not 100% sure, but I seem to remember that the determinant calculations are also quite sensitive to rounding (not if all you care about are integer x values of course). Again, this becomes more of a problem as the dimension goes up.
