    \[9x-8y=4\] \[2x-3y=-4\] There are several ways to solve this including matrices but the simplest way to do this would be to solve one of these for one variable and then plug that into another. You could also solve this using that as a system of equations and multiply one of the equations by a constant that will cause one of the variables to disappear when the equations are added are subtracted. Your choice
