**MathMate**, Friday, April 8, 2011 at 8:28amThe denominator is composed of a determinant made up of the left-hand side of the equation.

The numerator of the variables is made up a determinant of the left-hand side, but with the corresponding column replaced with the vector of the right hand side.
