Absolute Value Equations - Problem 5 199 views
To solve an absolute value equation, you will want to follow three steps: first, isolate the absolute value expression by "undoing" what is going on outside the absolute value. Next, replace the absolute value signs with +- ( ) . Then separate the + - into two different equations and solve each one separately. If done correctly, you could have no solutions or one solution, but most often, you'll have two solutions. They could be positive or negative. Substitute each of these separately back in for x to make sure your work is correct.
