\SOLVELINEARSYSTEM(1,-1,2;3,0,5;-1,1,4)%
                  (-4,4,-2)%
                  (\sola,\solb,\solc)
Solving the linear system
\[
\begin{bmatrix}
      1 & -1 & 2 \\ 3 & 0 & 5 \\ -1 & 1 & 4
     \end{bmatrix}\mathsf{X}=\begin{bmatrix}
      -4\\4\\-2
     \end{bmatrix}
\]
we obtain
$\mathsf{X}=\begin{bmatrix}
       \sola \\ \solb\\ \solc
     \end{bmatrix}$
