б) 3 5/6 - 1 1/12 * y = 1 17/24

б) \(3 \frac{5}{6} - 1 \frac{1}{12} \cdot y = 1 \frac{17}{24}\) \(\frac{23}{6} - \frac{13}{12} y = \frac{41}{24}\) \(-\frac{13}{12} y = \frac{41}{24} - \frac{23}{6}\) \(-\frac{13}{12} y = \frac{41 - 92}{24}\) \(-\frac{13}{12} y = \frac{-51}{24}\) \(y = \frac{-51}{24} : (-\frac{13}{12})\) \(y = \frac{51}{24} \cdot \frac{12}{13}\) \(y = \frac{51 \cdot 12}{24 \cdot 13}\) \(y = \frac{612}{312}\) \(y = \frac{51}{26} = 1 \frac{25}{26}\)
