$\frac {4}{9}(1 \frac{1}{2} \cdot c -\frac {3}{8})-(1\frac{5}{6}-1\frac{1}{3} \cdot c) = \frac {4}{9}( \frac{3}{2} \cdot c -\frac {3}{8})-( \frac{11}{6}-\frac{4}{3} \cdot c) = \\ ( \frac {4}{9} \cdot \frac{3}{2} \cdot c - \frac {4}{9} \cdot \frac {3}{8})-( \frac{11}{6}-\frac{4}{3} \cdot c) = \frac {2}{3} \cdot c - \frac {2}{3} - \frac {11}{6} + \frac {4}{3} \cdot c = \\ \frac {2+4}{3} \cdot c - \frac {4}{6} - \frac {11}{6} = 2c-2$ Дважды перепроверил... Надеюсь нет ошибок.
