Ответ:
а)
\((6 + 3x) : 16 = 6\).
\(6 + 3x = 6 \cdot 16 = 96\).
\(3x = 96 - 6 = 90\).
\(x = 90 : 3 = 30\).
Проверка: \((6 + 30 \cdot 3) : 16 = (6 + 90) : 16 = 96 : 16 = 6\).
б)
\(600 : (24 - x) = 36\).
\(24 - x = 600 : 36 = \frac{50}{3}\).
\(x = 24 - \frac{50}{3} = \frac{72}{3} - \frac{50}{3} = \frac{22}{3} = 7\frac{1}{3}\).
Проверка: \(600 : (24 - \frac{22}{3}) = 600 : \frac{50}{3} = 36\).
Ответ: а) \(x = 30\); б) \(x = \frac{22}{3}=7\frac{1}{3}\).
