Using Simultaneous Equation Solver

This will sound similar to the third section of the ESC Key Tutorial, well thats because the equation solver is ESC Key is identical to this program.

We have designed the Simultaneous Equation Solver to be simple to use.
The three input boxes are where you input the equations. These are located on the left hand side of the screen. If you are using two equations then leave the bottom box empty.

Input your equations using the following formats:

For two equations:
2X+4Y=50
Or
X+Y=5

For three equations:
2X+3Y-4Z=20
Or
X+Y+2Z=50
Or
0X+Y+3Z=80

Remember these four simple rules:

No Spaces
Always ensur all of the X's, Y's and Z's are there for three equations, X's and Y's for two equations.
The numbers, +'s and -'s can be changed
You must use X, Y and Z nothing else

Once you have entered all your equations either hit enter or click "Calculate"

For both two and three simultaneous equations this program uses Gaussian Elimination
