Exercise 48 Page 116

We are asked to find and graph the solution set for all possible values of

x

in the given inequality.

6 - ∣ x + 7 ∣ \leq - 2

Let's start with isolating an absolute value expression on one side of inequality.

6 - ∣ x + 7 ∣ \leq - 2

$LHS - 6 \leq RHS - 6$

- ∣ x + 7 ∣ \leq - 8

Divide by $- 1$ and flip inequality sign

∣ x + 7 ∣ \geq 8
