222. Решите уравнение: а) 8 8/11 - z = 3 9/11 б) y - 4 3/5 = 2 4/5 в) 8 16/27 - (x - 2 17/27) = 8 5/27

а) 8 \(\frac{8}{11}\) - z = 3 \(\frac{9}{11}\) z = 8 \(\frac{8}{11}\) - 3 \(\frac{9}{11}\) = 7 + 1 + \(\frac{8}{11}\) - 3 \(\frac{9}{11}\) = 7 + \(\frac{11}{11}\) + \(\frac{8}{11}\) - 3 \(\frac{9}{11}\) = 7 \(\frac{19}{11}\) - 3 \(\frac{9}{11}\) = 4 \(\frac{10}{11}\) Ответ: z = 4 \(\frac{10}{11}\) б) y - 4 \(\frac{3}{5}\) = 2 \(\frac{4}{5}\) y = 2 \(\frac{4}{5}\) + 4 \(\frac{3}{5}\) = 6 \(\frac{7}{5}\) = 6 + 1 \(\frac{2}{5}\) = 7 \(\frac{2}{5}\) Ответ: 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 \(\frac{5}{27}\) = \(\frac{11}{27}\) x = \(\frac{11}{27}\) + 2 \(\frac{17}{27}\) = 2 \(\frac{28}{27}\) = 3 \(\frac{1}{27}\) Ответ: x = 3 \(\frac{1}{27}\)
