282. Решите уравнение: 1) x + 7 4/15 = 9 7/10; 2) 8 9/14 − x = 4 3/7; 3) x − 3 8/9 = 5 1/12.

1. \(x=9\frac{7}{10}-7\frac{4}{15}=2+\frac{21}{30}-\frac{8}{30}=2\frac{13}{30}\).
2. \(x=8\frac{9}{14}-4\frac{3}{7}=4+\frac{9}{14}-\frac{6}{14}=4\frac{3}{14}\).
3. \(x=5\frac{1}{12}+3\frac{8}{9}=8+\frac{3}{36}+\frac{32}{36}=8\frac{35}{36}\).

Ответ: 1) \(x=2\frac{13}{30}\); 2) \(x=4\frac{3}{14}\); 3) \(x=8\frac{35}{36}\).
