Linear Equations

Author: Aaron Nunley
Description:

This lesson is designed to provide students with a clear explanation of how to work with linear equations.  I have a lot of students who are missing school due to illness currently and I am using this as an alternative means of instruction.  I will be adding to the lesson as time permits, and will be rearranging as I go.  Please pardon any gaps as my priority is to focus on topics currently being missed.

Thanks!
