Решение:

1. \(x + 798 = 3624\)
   \(x = 3624 - 798\)
   \(x = 2826\)
2. \(x - 2867 = 5684\)
   \(x = 5684 + 2867\)
   \(x = 8551\)
3. \(42410 - x = 5684\)
   \(x = 42410 - 5684\)
   \(x = 36726\)
4. \(507 \cdot y = 405600\)
   \(y = 405600 : 507\)
   \(y = 800\)
5. \(y : 807 = 480\)
   \(y = 480 \cdot 807\)
   \(y = 387360\)
6. \(6305 + y = 8510\)
   \(y = 8510 - 6305\)
   \(y = 2205\)
7. \(x - 1506 = 910\)
   \(x = 910 + 1506\)
   \(x = 2416\)
8. \(1006 - b = 897\)
   \(b = 1006 - 897\)
   \(b = 109\)
9. \(x \cdot 365 = 75190\)
   \(x = 75190 : 365\)
   \(x = 206\)
10. \(118610 : x = 290\)
    \(x = 118610 : 290\)
    \(x = 409\)
11. \(x + 574 = 2000\)
    \(x = 2000 - 574\)
    \(x = 1426\)
12. \(a - 879 = 3143\)
    \(a = 3143 + 879\)
    \(a = 4022\)
13. \(253 \cdot y = 86020\)
    \(y = 86020 : 253\)
    \(y = 340\)
14. \(x : 36 = 225\)
    \(x = 225 \cdot 36\)
    \(x = 8100\)
15. \(135 : x = 27\)
    \(x = 135 : 27\)
    \(x = 5\)
