No thank you.

An online program for solving systems of equations shows the solutions are very ugly fractions; specifically, z is a fraction with numerator and denominator each 6 digits. It will be a waste of time for either me or you to try to solve the system using Gauss-Jordan.

The Gauss-Jordan process is straightforward, but there are always endless variations on the sequence of steps used to find a solution.

Find a simpler system of equations for getting practice using the process.
