Solution
We begin by solving the absolute value inequality:
This inequality means that the expression inside the absolute value, , lies within 2 units of 0. To remove the absolute value, we rewrite the inequality as a compound inequality:
Now, solve for by adding 4 to all three parts of the inequality:
Thus, the solution is:
This is the compound inequality that describes the solution set.
