Linear System Solver

This application helps students or any person who needs,
to solve a system of 3 linear equation with 3 unknowns.
A system of linear equations is of this type:
/
| a11.x + a12.y + a13.z = c1
| a21.x + a22.y + a23.z = c2
| a31.x + a32.y + a33.z = c3
\
Values are required for x,y,z which satisfy the 3 equations.

In the application skema, insert the matrix coefficients:
a11 a12 a13
a21 a22 a23
a31 a32 a33
and next insert the constant values:
c1 c2 c3

Finally, hit the Solve button.
If the system has a real solution, this will be shown (x,y,z) in the last row.
If no real solution exists, NO,NO,NO will be shown.
