Solution

\frac{n}{4} \leq 3

Solution

- 12 \leq n \leq 12

+1

Interval Notation

[- 12, 12]

Solution steps

\frac{n}{4} \leq 3

Apply absolute rule: If

∣ u ∣ \leq a, a > 0

then

- a \leq u \leq a

- 3 \leq \frac{n}{4} \leq 3

\frac{n}{4} \geq - 3 and \frac{n}{4} \leq 3

n \geq - 12 and n \leq 12
