Решите уравнение: а) 1 1/3 - x = 2 5/6; б) -2 2/7 + x = -4 1/14.

а) (1 \frac{1}{3} - x = 2 \frac{5}{6}) \(\frac{4}{3} - x = \frac{17}{6}\) \(- x = \frac{17}{6} - \frac{4}{3}\) \(- x = \frac{17}{6} - \frac{8}{6}\) \(- x = \frac{9}{6}\) \(- x = \frac{3}{2}\) \(x = - \frac{3}{2} = -1 \frac{1}{2}\) б) (-2 \frac{2}{7} + x = -4 \frac{1}{14}) \(-\frac{16}{7} + x = -\frac{57}{14}\) \(x = -\frac{57}{14} + \frac{16}{7}\) \(x = -\frac{57}{14} + \frac{32}{14}\) \(x = -\frac{25}{14} = -1 \frac{11}{14}\)
