Math Problem Statement

∣x−3∣≤13

Solution

To solve the inequality x313|x - 3| \leq 13, we will break it down into two cases, as is common with absolute value inequalities.

Step 1: Rewrite the inequality

The inequality x313|x - 3| \leq 13 means that the expression inside the absolute value, x3x - 3, must lie between 13-13 and 1313. This can be rewritten as: 13x313-13 \leq x - 3 \leq 13

Step 2: Solve for xx

Now, solve for xx by adding 3 to all parts of the inequality: 13+3x3+313+3-13 + 3 \leq x - 3 + 3 \leq 13 + 3 10x16-10 \leq x \leq 16

Solution

The solution is: x[10,16]x \in [-10, 16]

This means xx is between 10-10 and 1616, inclusive.

Tip: When solving absolute value inequalities, always remember to split the inequality into two cases—one for the positive and one for the negative value inside the absolute value.
