##### Description:

By the end of this tutorial, students will be able to solve absolute value equations with one variable.

Students will be able to substitute both values back into the original equation to verify they are correct.

This podcast is an introduction to solving absolute value equations with one variable.  Students will use PEMDAS and the balance method to find the two possible solutions to each equation.

Tutorial

## TO DO:

Watch the video and/or slides below and take notes.

## ABSOLUTE VALUE - Solving Equations

This video walks students through solving absolute value equations, finding both possible answers and checking the answer using substitution.

The video lays out four simple steps:

1) Balance to get the absolute value alone
2) Write two equations (one positive absolute value, one negative)
3) Balance the two equations

The video works through four examples.

## Extraneous Solutions
