Solution

d \leq - 12 or d \geq - 4

+1

Interval Notation

(- \infty, - 12] \cup [- 4, \infty)

Solution steps

5 ∣ d + 8 ∣ - 7 \geq 13

Move

7

to the right side

5 ∣ d + 8 ∣ \geq 20

Divide both sides by

5

∣ d + 8 ∣ \geq 4

Apply absolute rule: If

∣ u ∣ \geq a, a > 0

then

u \leq - a

or

u \geq a

d + 8 \leq - 4 or d + 8 \geq 4

d + 8 \leq - 4 or d + 8 \geq 4

d \leq - 12 or d \geq - 4
