I'm in need of help if it would be possible to help me out.
I'm looking for a way to solve a linear equation with n variables using a PHP Open source code. For example:
1.x1 + 1.x2 + 4.x3 + 8.x4 + 12.x5 + 22.x6 ... + 13.xn = y1
2.x1 + 3.x2 + 8.x3 + 6.x4 + 28.x5 + 28.x6 ... + 11.xn = y2
6.x1 + 1.x2 + 1.x3 + 3.x4 + 34.x5 + 34.x6 ... + 21.xn = y3
8.x1 + 4.x2 + 3.x3 + 1.x4 + 21.x5 + 13.x6 ... + 18.xn = yn
Could somebody please help me out, I would be really gratefull. I have already spent 2 days looking for this but to no avail.
