Hi there:

 

I have a short question. For an algorithm, I need a solution to a linear equation, and I use LinearAlgebra[LinearSolve]. In the case of

 

0            0                    0

                       =      

5            0                    0

 

for example, there are infinitely many, however, so Maple returns (_t2,0). My algorithm just needs one solution, if there are multiple ones, then any (except for _t2=0) is fine. However, if (_t2,0) is the saved solution, the algorithm later breaks down, since it does not expect the extra variable. Is there any way to tell Maple to replace every variable with, say, 1 when solving such an equation?
