Answer 2

\(3\dfrac{2}{3}\cdot\left(\dfrac{1}{5}-\dfrac{1}{2}\right)< x< \dfrac{3}{11}\cdot\left(\dfrac{1}{5}+\dfrac{2}{3}-\dfrac{1}{2}\right)\\ \dfrac{11}{3}\cdot\left(\dfrac{1}{5}-\dfrac{1}{2}\right)< x< \dfrac{3}{11}\cdot\left(\dfrac{1}{5}+\dfrac{2}{3}-\dfrac{1}{2}\right)\\ \dfrac{11}{3}\cdot\dfrac{-3}{10}< x< \dfrac{3}{11}\cdot\dfrac{11}{30}\\ \dfrac{-11}{10}< x< \dfrac{1}{10}\\ \Rightarrow x\in\left\{-1;0\right\}\)
