Example Question #22 : Inequalities

Possible Answers:

 or 

Correct answer:

Explanation:

The first thing we must do is get the absolute value alone: 

When we're working with absolute values, we are actually solving two equations:

     and 

Fortunately, these can be written as one equation:

If you feel more comfortable solving the equations separately then go ahead and do so.

              To get  alone, we added  on both sides of the inequality sign
