Solve the inequality

|0.2x+6| <0.15

- 30.75 < x < - 29.25

Step-by-step explanation:

Inequalities of the type | x | < a, always have solutions of the form

- a < x < a

Given

| 0.2x + 6 | < 0.15, then

- 0.15 < 0.2x + 6 < 0.15 (subtract 6 from all 3 intervals)

- 6.15 < 0.2x < - 5.85 (divide all intervals by 0.2)

- 30.75 < x < - 29.25
