In absolute-value problems such as this one, you need first to remove the absolute-value bars. When you do this, you will get two inequalities, for example:
Remove the bars.
or .
So for your problem:
Remove the bars.
or Now solve these two inequalities by dividing both sides by 5.
or So the Interval would be:
(-5 < x < 5)
(-5, 5)
