Tutoring math at CSUMB, systems of equations and quadratic equations

We started by looking at systems of two equations with two variables and using substitution to solve.

Then did a few problems with three equations and three variables.

Also used u-substitution to solve a few quadratic equations. If they can be factored, that can be easier. Sometimes quadratic equations cannot be easily factored, in which case it can be useful to use the Quadratic Formula.
