Start with the given inequality

Break up the absolute value (remember, if you have , then and )

and Break up the absolute value inequality using the given rule

Combine the two inequalities to get a compound inequality

Subtract 4 from all sides

Divide all sides by -1. This will isolate x. Remember, dividing by a negative number flips the inequality signs.

Rearrange the inequality

Answer:

So our answer is

which looks like this in interval notation

if you wanted to graph the solution set, you would get
