-6<-2/5 (1-x)<= 4

- 6 < - \frac{2}{5} (1 - x) \leq 4

- 14 < x \leq 11

Solution steps

- 6 < - \frac{2}{5} (1 - x) \leq 4

a < u \leq b

then

a < u and u \leq b

- 6 < - \frac{2}{5} (1 - x) and - \frac{2}{5} (1 - x) \leq 4

- 6 < - \frac{2}{5} (1 - x) : x > - 14

- \frac{2}{5} (1 - x) \leq 4 : x \leq 11

Combine the intervals

x > - 14 and x \leq 11

Merge Overlapping Intervals

- 14 < x \leq 11

2 (4) - 3 (x - 1) = - 1

(\frac{3 a}{b})^{4}

\frac{3 r ^{2} p ^{6}}{t ^{4}} + \frac{4 r ^{2} p ^{6}}{t ^{4}}

(x - 2)^{2} (x + 1)^{3} (x + 5) \leq 0

\frac{2}{5} - \frac{1}{2}
