|(6-5x)/(x+3)|<= 1/2

\frac{6 - 5 x}{x + 3} \leq \frac{1}{2}

\frac{9}{11} \leq x \leq \frac{5}{3}

Interval Notation

[\frac{9}{11}, \frac{5}{3}]

Decimal Notation

0.81818 \dots \leq x \leq 1.66666 \dots

Solution steps

\frac{6 - 5 x}{x + 3} \leq \frac{1}{2}

Apply absolute rule: If

∣ u ∣ \leq a, a > 0

then

- a \leq u \leq a

- \frac{1}{2} \leq \frac{6 - 5 x}{x + 3} \leq \frac{1}{2}

\frac{6 - 5 x}{x + 3} \geq - \frac{1}{2} and \frac{6 - 5 x}{x + 3} \leq \frac{1}{2}

- 3 < x \leq \frac{5}{3} and (x < - 3 or x \geq \frac{9}{11})

Merge Overlapping Intervals

\frac{9}{11} \leq x \leq \frac{5}{3}

x^{2} + 3 x - 12 = 0
