## Gaussian Elimination:

In Gaussian elimination, we construct an augmented matrix and perform row reduction methods until we have a triangular matrix. This method is useful in finding solutions to systems of equation. This method was named after Carl Friedrich Gauss.

For this problem, we need to identify the system of equations that we are going to solve.

Let {eq}x = {/eq} number of children, {eq}y = {/eq} number...
