Welcome to the Linear Equation Solver

Please enter a system to solve, and click when you're done.
A Quick Guide


Let's say you have the following system of equations:
   x + y = √2 + z
   x + sin(/3)y + 7z = 2y
   y + z = -1

You have to get it into the following form before you can enter it in to the solver:
   1x +        1y + -1z =  √2
   2x + sin(/3)y +  7z =  0
   0x +        1y +  1z = -1

Then just enter in
   1            1  -1
   2  sin(2*pi/3)   7
   0            1   1

in the first box. Then, type
   x
   y
   z

in the second box, and finally, place
   sqrt(2)
   0
  -1

in the last box. Hit "Process" and prepare to be amazed.

The functions, operators, and constants available for use are as follows (you can also use parentheses for clarity if you wish):
