Answer:
- 10 < x < 7
Step-by-step explanation:
Inequalities of the type | x | < a
Always have solutions of the form
- a < x < a
Given
| 2x + 3 | - 5 < 12 ( add 5 to both sides )
| 2x + 3 | < 17 , then
- 17 < 2x + 3 < 17 ( subtract 3 from all 3 intervals )
- 20 < 2x < 14 ( divide the 3 intervals by 2 )
- 10 < x < 7
