5.268. Решите уравнение: 1) (654x - 10 590) : 57 = 778; 2) (54x + 22) \cdot 315 = 23940.

1) \((654x - 10590):57 = 778\) \(654x - 10590 = 778 \cdot 57\) \(654x - 10590 = 44346\) \(654x = 44346 + 10590\) \(654x = 54936\) \(x = \frac{54936}{654}\) \(x = 84) 2) \((54x + 22) \cdot 315 = 23940\) \(54x + 22 = \frac{23940}{315}\) \(54x + 22 = 76\) \(54x = 76 - 22\) \(54x = 54\) \(x = \frac{54}{54}\) \(x = 1\)
