1 вариант. 2. Решите уравнения 1) \(x + 3 \frac{4}{13} = 5 \frac{10}{13}\) 2) \(4 \frac{2}{5} - x = 3 \frac{3}{5}\) 3) \(2 \frac{2}{5} x = \frac{8}{13}\)

**2. Решите уравнения** 1) \(x + 3 \frac{4}{13} = 5 \frac{10}{13}\) \(x = 5 \frac{10}{13} - 3 \frac{4}{13}\) \(x = (5-3) + (\frac{10}{13} - \frac{4}{13})\) \(x = 2 + \frac{6}{13}\) \(x = 2 \frac{6}{13}\) 2) \(4 \frac{2}{5} - x = 3 \frac{3}{5}\) \(x = 4 \frac{2}{5} - 3 \frac{3}{5}\) \(x = 4 \frac{2}{5} - 3 \frac{3}{5} = 4 - 3 + \frac{2}{5} - \frac{3}{5} = 1 - \frac{1}{5} = \frac{5}{5} - \frac{1}{5} = \frac{4}{5}\) \(x = \frac{4}{5}\) 3) \(2 \frac{2}{5} x = \frac{8}{13}\) \(\frac{12}{5} x = \frac{8}{13}\) \(x = \frac{8}{13} : \frac{12}{5}\) \(x = \frac{8}{13} \cdot \frac{5}{12}\) \(x = \frac{8 \cdot 5}{13 \cdot 12} = \frac{2 \cdot 5}{13 \cdot 3} = \frac{10}{39}\) \(x = \frac{10}{39}\)
