Solving a System of Quadratic Equations using Substitution

Quadratic systems can be solved using substitution just like linear-quadratic systems. One equation is substituted into the other, resulting in either a quadratic or linear equation. The solution to the resulting equation gives the -values for the solution to the entire system. Lastly, they are substituted into one of the original equations to find the corresponding -values.
