### Solving by Elimination - 26:16

This video looks at solving by elimination from its simplest form, to solving with decimals and fractions. Note that Sample Problem 3 and 4 are not a step by step to completion. These sample problems merely assist with the initial steps to converting decimals and fractions into linear systems similar to Sample Problems 1 and 2. Answers are provided.

### Solving by Substitution - 22:48

### Solving by Graphing - 14:43

### Introduction to Linear Systems - 7:18

In this video, I introduce the 3 possible outcomes when solving linear systems. Linear systems are a set of 2 or more lines and it is up to us to determine where these lines will intersect one another, IF they will in fact intersect one another. This lesson is to be watched prior to watching my videos on Solving by Graphing, Substitution and Elimination.
