Solving Linear Systems with Substitution and Linear Combination (Simultaneous Equations)

I take a system of linear equations and show you how to solve it with substition and then with linear combination. I show how you could find one answer, no answer, or many answers. Check out http://www.ProfRobBob.com/, there you will find my lessons organized by class/subject and then by topics within each class.
