3. Реши уравнения: (x + 275) − 468 = 593; 7 × (x − 148) = 2 464; (960 − x) : 8 = 75.

1. \((x + 275) - 468 = 593\)
   \(x + 275 = 593 + 468 = 1\,061\)
   \(x = 1\,061 - 275 = 786\)
2. \(7(x - 148) = 2\,464\)
   \(x - 148 = 2\,464 : 7 = 352\)
   \(x = 352 + 148 = 500\)
3. \((960 - x) : 8 = 75\)
   \(960 - x = 75 \times 8 = 600\)
   \(x = 960 - 600 = 360\)

Ответ: 786; 500; 360.
