Compare and contrast solving a system of three equations to solving a system of two equations.

Comparations: You are still solving for variables in both systems of equations, You can still use the substitution and elimination method for both systems to solve for the variables. Contrasts: With a system of three equations, you are solving for 3 variables, whereas a system of two equations you are solving for 2 variables. While both are a similar process, solving a system of three equations is much lengthier process because you are solving for more variables.
