Question statement

Solve the system of equations using Gaussian Elimination

$\begin{eqnarray} &x&+\;&\var{b}y&+\;\var{b*a-b}z&=&\var{c3}\\ &\var{a}x&+\;&\var{a*b-1}y&+\;\var{a^2*b-a-a*b}z&=&\var{c2}\\&\var{a*c}x&+\;&\var{c*b}y&+\;z&=&\var{c1} \end{eqnarray}$

Give any introductory information the student needs.
