2 вариант. 2. Решите уравнения 1) \(2 \frac{3}{11} + x = 4 \frac{7}{11}\) 2) \(x - 3 \frac{2}{5} = 2 \frac{3}{5}\) 3) \(3 \frac{1}{3} x = \frac{10}{11}\)

**2. Решите уравнения** 1) \(2 \frac{3}{11} + x = 4 \frac{7}{11}\) \(x = 4 \frac{7}{11} - 2 \frac{3}{11}\) \(x = (4-2) + (\frac{7}{11} - \frac{3}{11})\) \(x = 2 + \frac{4}{11}\) \(x = 2 \frac{4}{11}\) 2) \(x - 3 \frac{2}{5} = 2 \frac{3}{5}\) \(x = 2 \frac{3}{5} + 3 \frac{2}{5}\) \(x = (2+3) + (\frac{3}{5} + \frac{2}{5})\) \(x = 5 + \frac{5}{5}\) \(x = 5 + 1\) \(x = 6\) 3) \(3 \frac{1}{3} x = \frac{10}{11}\) \(\frac{10}{3} x = \frac{10}{11}\) \(x = \frac{10}{11} : \frac{10}{3}\) \(x = \frac{10}{11} \cdot \frac{3}{10}\) \(x = \frac{10 \cdot 3}{11 \cdot 10} = \frac{1 \cdot 3}{11 \cdot 1} = \frac{3}{11}\) \(x = \frac{3}{11}\)
