4. Решите уравнение: A) y-5\frac{5}{9} = 6\frac{5}{9} Б) (x-2\frac{11}{13})+5\frac{5}{13} = 8\frac{2}{13}

Решим уравнения:

1. y - 5\(\frac{5}{9}\) = 6\(\frac{5}{9}\)

y = 6\(\frac{5}{9}\) + 5\(\frac{5}{9}\)

y = 11\(\frac{10}{9}\)

y = 12\(\frac{1}{9}\)

2. (x - 2\(\frac{11}{13}\)) + 5\(\frac{5}{13}\) = 8\(\frac{2}{13}\)

x - 2\(\frac{11}{13}\) = 8\(\frac{2}{13}\) - 5\(\frac{5}{13}\)

x - 2\(\frac{11}{13}\) = 2\(\frac{10}{13}\)

x = 2\(\frac{10}{13}\) + 2\(\frac{11}{13}\)

x = 4\(\frac{21}{13}\)

x = 5\(\frac{8}{13}\)

Ответ: 1) y = 12\(\frac{1}{9}\); 2) x = 5\(\frac{8}{13}\)
