Решение уравнения:
\(y - \frac{7}{12}y = 4 \frac{1}{6}\)
\(\frac{12}{12}y - \frac{7}{12}y = \frac{25}{6}\)
\(\frac{5}{12}y = \frac{25}{6}\)
\(y = \frac{25}{6} : \frac{5}{12}\)
\(y = \frac{25}{6} \cdot \frac{12}{5}\)
\(y = \frac{25 \cdot 12}{6 \cdot 5}\)
\(y = \frac{5 \cdot 5 \cdot 2 \cdot 6}{6 \cdot 5}\)
\(y = 5 \cdot 2 = 10\)
Ответ: \(y = 10\)
