2. Решите уравнение \(y - \frac{7}{12}y = 4\frac{1}{6}\).
- \(y - \frac{7}{12}y = 4\frac{1}{6}\)
- \(\frac{12}{12}y - \frac{7}{12}y = \frac{4 \cdot 6 + 1}{6}\)
- \(\frac{5}{12}y = \frac{25}{6}\)
- \(y = \frac{25}{6} : \frac{5}{12}\)
- \(y = \frac{25}{6} \cdot \frac{12}{5}\)
- \(y = \frac{25 \cdot 12}{6 \cdot 5}\)
- \(y = \frac{5 \cdot 2}{1 \cdot 1}\)
- \(y = 10\)
- Ответ: 10
