Solving a system of three linear equations in 3 unknowns using Gauss Elimination in 4 stages. Solutions are all integral.

A simultaneous equations question with integers only

Solve for $x$ and $y$:  \[ \begin{eqnarray} a_1x+b_1y&=&c_1\\   a_2x+b_2y&=&c_2 \end{eqnarray} \]

The included video describes a more direct method of solving when, for example, one of the equations gives a variable directly in terms of the other variable.

Putting a pair of linear equations into matrix notation and then solving by finding the inverse of the coefficient matrix. 

Shows how to define variables to stop degenerate examples.
