Solutions of Simultaneous Equations

This program solves simultaneous linear equations in two or three unknowns.
It does this through matrix inversion and matrix multiplication.
A system of three linear equations
can be represented by the matrix equation below.
The matrix equation may be solved for X, Y, and Z by multiplying the result
matrix by the inverse of the coefficient matrix.
Specifics regarding the inversion process are given in the comments for the
inversion routine, I.
