222. Решите уравнение: a) 8/11 - x - 2 3/11; б) y - 4 3/5 = 2 4/5; в) 8 16/27 - (x - 2 17/27) = 8 5/27.

а) $$\frac{8}{11} - x = 2\frac{3}{11}$$

$$x = \frac{8}{11} - 2\frac{3}{11}$$

$$x = \frac{8}{11} - \frac{25}{11}$$

$$x = \frac{8 - 25}{11}$$

$$x = \frac{-17}{11}$$

$$x = -1\frac{6}{11}$$

б) $$y - 4\frac{3}{5} = 2\frac{4}{5}$$

$$y = 4\frac{3}{5} + 2\frac{4}{5}$$

$$y = 6\frac{7}{5}$$

$$y = 7\frac{2}{5}$$

в) $$8\frac{16}{27} - (x - 2\frac{17}{27}) = 8\frac{5}{27}$$

$$x - 2\frac{17}{27} = 8\frac{16}{27} - 8\frac{5}{27}$$

$$x - 2\frac{17}{27} = \frac{11}{27}$$

$$x = \frac{11}{27} + 2\frac{17}{27}$$

$$x = 2\frac{28}{27}$$

$$x = 3\frac{1}{27}$$

Ответ: а) $$-1\frac{6}{11}$$; б) $$7\frac{2}{5}$$; в) $$3\frac{1}{27}$$
