Create your system of linear equations then write a brief paper describing the system

Required Materials

Click here for a PowerPoint presentation on solving systems of linear equations.

After thoroughly reviewing the examples in the PowerPoint presentation, go through these two introductory tutorials below:

The Hofstra webpage has a good tutorial on systems of linear equations. You can skip portions that discuss matrices and matrix algebra, as you won't be required to know this. Their applications of linear equations section is also worth looking at.

The ThinkQuest Library has a Page on Systems of Equations that is worth going through.

Here is a good site that discusses solving systems of linear equations.

These following two links below are good for reviewing some of the basic formulas:

This page from S.O.S. Math on Systems of Equations in Two Variables is a good overview.

Optional Materials

Mathpower.com has a good collection of tutorials prepared by students for students for a variety of topics. So if your professor's explanations are not clear to you, maybe these tutorials will be clear to you. There are a number of tutorials on solving systems of equations at the bottom of this page.

Math.com has a lot of useful background material for those of you who wish to refresh your basic math skills such as fractions, percents, etc.
