Ta có: \(-4\frac23\cdot\left(\frac12-\frac16\right)\le x\le-\frac23\cdot\left(\frac13-\frac12-\frac34\right)\)
=>\(-\frac{14}{3}\cdot\left(\frac36-\frac16\right)\le x\le-\frac23\left(\frac{4}{12}-\frac{6}{12}-\frac{9}{12}\right)\)
=>\(-\frac{14}{3}\cdot\frac13\le x\le-\frac23\cdot\frac{-11}{12}\)
=>\(-\frac{14}{9}\le x\le\frac{22}{36}=\frac{11}{18}\)
mà x nguyên
nên x∈{-1;0}
