Решить уравнения: x + 798 = 3624; k − 2867 = 5684; 42410 − x = 5684; 507 · y = 405600; y : 807 = 480.

1. \(x + 798 = 3624\)
   \(x = 3624 - 798 = 2826\).
2. \(k - 2867 = 5684\)
   \(k = 5684 + 2867 = 8551\).
3. \(42410 - x = 5684\)
   \(x = 42410 - 5684 = 36726\).
4. \(507 \cdot y = 405600\)
   \(y = 405600 : 507 = 800\).
5. \(y : 807 = 480\)
   \(y = 480 \cdot 807 = 387360\).

Ответ: \(x=2826\); \(k=8551\); \(x=36726\); \(y=800\); \(y=387360\).
