+1

Interval Notation

[- 5, - 1]

Solution steps

3 ∣ x + 3 ∣ + 7 \leq 13

Move

7

to the right side

3 ∣ x + 3 ∣ \leq 6

Divide both sides by

3

∣ x + 3 ∣ \leq 2

Apply absolute rule: If

∣ u ∣ \leq a, a > 0

then

- a \leq u \leq a

- 2 \leq x + 3 \leq 2

x + 3 \geq - 2 and x + 3 \leq 2

x \geq - 5 and x \leq - 1

Merge Overlapping Intervals

- 5 \leq x \leq - 1
