Solving Linear-Quadratic Systems by Substitution (i.e. the best way!)

In this video, I show you how to set up and solve linear-linear and liner-quadratic systems analytically using the substitution method.

This is probably the BEST method to solve systems of equations. It always works, usually in (close to) the fewest steps possible, and you'll get EXACT answers every time. (Even using technology to graph, you usually only get approximate solutions.)

That said, understanding what solutions mean should also be understood graphically, which is why both skills are usually taught together!
