Question

Tìm x biết: -8/15< x/15 < -2//15

Answer 1

\(-\frac{8}{15}< \frac{x}{15}< -\frac{2}{15}\)

=> \(-8< x< -2\)

=> \(x\in\left\{-7;-6;-5;-4;-3\right\}\)

Answer 2

Ta có : \(\frac{-8}{15}< \frac{x}{15}< \frac{-2}{15}\)

\(\Rightarrow-8< x< -2\)

\(\Rightarrow x\in\left\{-7;-6;-5;-4;-3\right\}\)

Vậy \(x\in\left\{-7;-6;-5;-4;-3\right\}\)
