Реши уравнения: x + 15 = 56 − 4; x : 14 = 7; 11 · x = 55; 196 − x = 46 + 5.

1. \(x + 15 = 56 - 4\); \(x + 15 = 52\); \(x = 52 - 15 = 37\).
2. \(x : 14 = 7\); \(x = 7 \cdot 14 = 98\).
3. \(11 \cdot x = 55\); \(x = 55 : 11 = 5\).
4. \(196 - x = 46 + 5\); \(196 - x = 51\); \(x = 196 - 51 = 145\).

Ответ: x = 37; x = 98; x = 5; x = 145.
