Solve |x-3| ≤ 5: Absolute Value Inequality Step-by-Step

Question

Given:

x35 |x-3| \leq 5

Which of the following statements is necessarily true?

Step-by-Step Solution

To solve the inequality x35 |x-3| \leq 5 , we need to consider the definition of absolute value inequalities. The inequality ab |a| \leq b translates to bab -b \leq a \leq b .

Applying this to our expression x35 |x-3| \leq 5 , we have:

5x35 -5 \leq x-3 \leq 5 .

We add 3 to all parts of the inequality to isolate x x :

5+3x3+35+3 -5 + 3 \leq x - 3 + 3 \leq 5 + 3

This simplifies to 2x8 -2 \leq x \leq 8 .

Answer

2x8 -2 \leq x \leq 8
