Hey, slightly new to the whole software of Mathematica, as well as programming, etc. And i've occured a simple problem in my need
It occures that whenever i try to calculate a set of equations with an unknown (set of) constant(s), (which normally would be done through hand) seem to eliminate the constant through the equations, leaving it with a wrong answer,
as an example i'd like to be able to compute the reduced solution for
x1+2x2+4x3+4*x4=b1
3x1+x2+7x3-3*x4=b2
2x1+x2+5x3-x4=b3
x1+x2+3*x3+x4=b4
or likewise, thanks in advance.
