Math Problem Statement
Solution
We are given the inequality .
Step-by-step solution:
-
Definition of absolute value inequality: For any , where , this means: So in this case, we can split the inequality into two parts:
-
Solving for :
-
First, solve the left inequality: Add 5 to both sides:
-
Now, solve the right inequality: Add 5 to both sides:
-
-
Combined inequality: Now, combining both results, we get: So, the solution is .
Graphing the solution:
- The solution represents an open interval between 2 and 8. On a number line:
- Open circles at and (since these are not included in the solution).
- A line segment between 2 and 8.

Tip:
When solving absolute value inequalities, always split them into two cases—one positive and one negative—and solve each case separately.
