7. Реши уравнения: \(3\frac{5}{11} - x = 1\frac{9}{11}\) \(y - 5\frac{4}{6} = 3\frac{2}{6}\) \(n + \frac{7}{8} = 5\frac{1}{8}\)

Решим первое уравнение: \(3\frac{5}{11} - x = 1\frac{9}{11}\) \(x = 3\frac{5}{11} - 1\frac{9}{11}\) \(x = 2\frac{16}{11} - 1\frac{9}{11}\) \(x = 1\frac{7}{11}\) Решим второе уравнение: \(y - 5\frac{4}{6} = 3\frac{2}{6}\) \(y = 3\frac{2}{6} + 5\frac{4}{6}\) \(y = 8\frac{6}{6}\) \(y = 9\) Решим третье уравнение: \(n + \frac{7}{8} = 5\frac{1}{8}\) \(n = 5\frac{1}{8} - \frac{7}{8}\) \(n = 4\frac{9}{8} - \frac{7}{8}\) \(n = 4\frac{2}{8}\) \(n = 4\frac{1}{4}\)
