Yeah, I’m gone today (10/15/12), but we still need to move on to Lesson 2.4, where we’ll be solving equations with variables on **both sides** of the equals sign. I’ve prepared three short videos that set up the lesson with example of the types of equations we’ll be solving.

## Example Video #1

Start with this video that shows a basic example and introduces a new step in our solving process:

**collecting variable terms on one side**.

## Example Video #2

The second video shows a more complicated equation, which will require **simplifying on both sides before solving**.

## Example Video #3

The final video examines two special situations that you may come across when all the variables in the equation cancel and you’re left with only constants (numbers).

## Assignment

Now that you’ve seen some of these equations, you need to practice them yourselves. The assignment for today is from page 103, **#1-13, 15-26**. Let’s make #1-13 due at the end of the period, just to keep you honest. You can do #15-26 on another sheet of paper. If you still need more examples, please check out **these video tutors** provided by Holt.
