Absolute Value Equations - YourTeacher.com - Algebra Help

For a complete lesson on solving absolute value equations, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that when solving an absolute value equation, such as 2 + I x + 1 I = 8, the first step is to isolate the absolute value by subtracting 2 from both sides to get I x + 1 I = 6. The next step is to split the equation up into two separate equations in the following way: x + 1 = 6 or x + 1 = -6. Notice that in the second equation, the 6 becomes negative. Finally, the last step is to solve each of the remaining equations to get x = 5 or x = -7.

This is too simple. I was looking for something with absolute values on both sides of the equation
