Summary:
When choosing between two competitive cell phone plans or two rental car offers, it helps to apply common sense-but a little algebra never hurt either. A multi-variable and multi-relation mathematical model, also known as a system, will do the trick. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video introduces students to systems of linear equations in two or three unknowns.  Read more...

Abstract:

When choosing between two competitive cell phone plans or two rental car offers, it helps to apply common sense-but a little algebra never hurt either. A multi-variable and multi-relation mathematical model, also known as a system, will do the trick. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video introduces students to systems of linear equations in two or three unknowns. The program features a variety of methods: four involve the TI-Nspire graphing calculator (spreadsheet, graphs and geometry, matrices, and nSolve) and two are the classic algebraic methods known as substitution and elimination, also called the linear combinations method. The video concludes with a summary of the three possible types of solutions.
