Solving determinant of a 3X3 using arrays

[slm843]

I a am trying to solve 3 simultaneous equation with 3 unknowns. The data for the equations must be entered as variables. If anyone is familiar with solving a dc network using mesh analysis, this is what is trying to be accomplised.

There is a method taught in most linear algebra books called Gaussian Elimination which solved the equation A*x = y for x. If you are using a computer, you should use this method. Of course for small systems (3x3) Kramers rule is often used for hand calculations. If you are going to code a solution use gaussian elimination.
