| 1/X+3|<= 4

Solution

\frac{1}{X} + 3 \leq 4

Solution

X \leq - \frac{1}{7} or X \geq 1

+2

Solution steps

\frac{1}{X} + 3 \leq 4

Apply absolute rule: If

∣ u ∣ \leq a, a > 0

then

- a \leq u \leq a

- 4 \leq \frac{1}{X} + 3 \leq 4

\frac{1}{X} + 3 \geq - 4 and \frac{1}{X} + 3 \leq 4

(X \leq - \frac{1}{7} or X > 0) and (X < 0 or X \geq 1)
