1. Problem Description

The problem asks to solve the absolute value inequality 2x+5<9|2x+5| < 9.

2. Solution Steps

The absolute value inequality 2x+5<9|2x+5| < 9 can be rewritten as a compound inequality:
9<2x+5<9-9 < 2x+5 < 9
We can solve this by isolating xx in the middle. First, subtract 55 from all three parts of the inequality:
95<2x+55<95-9 - 5 < 2x + 5 - 5 < 9 - 5
14<2x<4-14 < 2x < 4
Next, divide all three parts by 22:
142<2x2<42\frac{-14}{2} < \frac{2x}{2} < \frac{4}{2}
7<x<2-7 < x < 2

3. Final Answer

The solution to the inequality is 7<x<2-7 < x < 2.
