Solution

3 \leq ∣ 3 x - 15 ∣

Solution

x \leq 4 or x \geq 6

+1

Interval Notation

(- \infty, 4] \cup [6, \infty)

Solution steps

3 \leq ∣ 3 x - 15 ∣

Switch sides

∣ 3 x - 15 ∣ \geq 3

Apply absolute rule: If

∣ u ∣ \geq a, a > 0

then

u \leq - a

or

u \geq a

3 x - 15 \leq - 3 or 3 x - 15 \geq 3

3 x - 15 \leq - 3 or 3 x - 15 \geq 3

x \leq 4 or x \geq 6
