Matrix Calculator

From HyeSpirit:

No help files included so read the description
You can input equations like:

4x+5y=6
2y+x=7

Or

4x+2y+3z=6
x+y+z=7
x-y-z=5

And it will solve the equations using the matrix method.
For the 1st one it will solve for x and y
For the 2nd one it will solve for x,y and z
You can input equations with up to 9 variables
You can later view the steps that were involved in solving the equation. So it's basically for intermediate algebra students.
You'll need to simplify your equations before you can enter them (including decimals and fractions).
For example you cannot enter 5x+5-y=z
You'll need to enter it as: 5x-y-z=-5

I make no guarantees for the accuracy, all I can say is I tested the program with a lot of equations and it worked fine.

Hope it helps
