Cramer XL v1.1
By Joshua Foster
(c)2001 JF Productions

Cramer XL is a math utility you can use to find solutions
to linear equations using Cramer's Rule.  CXL works with
2-equation, 3-equation, and 4-equation problems.  Also,
if there is an answer, CXL will offer to create matrices
so you can see how the problem works.  There are two
available methods: DX/D (determinant D) and 1-matrix.

--Determinant D--
With determinant D, the matrices hold A's (B's, C's, D's)
in certain orders.  One matrix is the D matrix, and the
others are Dx, Dy, Dz, and Dw.  To find the X answer, for
example, you divide the determinant of the Dx matrix by
the determinant of the D matrix.

--1-matrix--
With 1-matrix, there are 2 matrices.  One matrix holds
every variable but the last ones of each equation (C, D, E).
The second matrix holds the last variables.  To solve
these matrices, you multiply the inverse (x-1 key) of
the first matrix ([A]) by the second matrix ([B]).

If you have any questions on how to use this program, or
