Question 12872
I hope you can follow this, but without a real problem, I am going to have to make one up.
<BR>
Cramers rule uses comparison of matricies in order to solve the problem, so if you had a system of equations like this one <BR>

ax + by = c
dx + fy = g

<BR>
You need to set up your 3 matricies first...

<B> Matrix 1: " D matrix" </B> {{{ abs(matrix(2,2, a, b, d, f)) }}}

<B> Matrix 2: "Dx matrix" </B> {{{ abs(matrix(2,2, c, g, d, f)) }}}

<B> Matrix 3: "Dy matrix" </B> {{{ abs(matrix(2,2, a, b, c, g)) }}}

Now here is how you find your X and Y Values
<BR>
{{{ X = Dx/D }}} {{{ Y = Dy/D }}}

Dx = the Determinant of your Dx Matrix
Dy = the Determinant of your Dy Matrix
D  = the determinant of your D  matrix

<BR>
Subsitute your Determininant into your the formulas under "Here's how to find your X and Y Values" simplfy and reduce your factions
