Question

Tìm x ϵ Z

\(\left(\frac{-3}{2}:\frac{3}{-1}\right).\left(\frac{-9}{2}\right)-\frac{1}{4}< \frac{x}{8}< \frac{-1}{2}.\frac{3}{4}:\frac{1}{8}+1\)

 

Answer 1

\(\left(-\frac{2}{3}:-\frac{1}{3}\right).\left(-\frac{9}{2}\right)-\frac{1}{4}< \frac{x}{8}< -\frac{1}{2}.\frac{3}{4}:\frac{1}{8}+1\)

\(2.\left(-\frac{9}{2}\right)-\frac{1}{4}< \frac{x}{8}< \left(-3\right)+1\)

\(\left(-9\right)-\frac{1}{4}< \frac{x}{8}< \left(-2\right)\)

\(\left(-\frac{37}{4}\right)< \frac{x}{8}< \left(-2\right)\)

\(-\frac{74}{8}< \frac{x}{8}< -\frac{16}{8}\)

            Vậy -74<x<-16
