Решение уравнений:

1. (4 ⋅ x – 1085) + 1193 = 2132

   4 ⋅ x – 1085 = 2132 – 1193

   4 ⋅ x – 1085 = 939

   4 ⋅ x = 939 + 1085

   4 ⋅ x = 2024

   x = 2024 : 4

   x = 506

2. (9 ⋅ y + 1069) – 1097 = 2375

   9 ⋅ y + 1069 = 2375 + 1097

   9 ⋅ y + 1069 = 3472

   9 ⋅ y = 3472 – 1069

   9 ⋅ y = 2403

   y = 2403 : 9

   y = 267

3. (7273 – 5 ⋅ m) – 4219 = 1724

   7273 – 5 ⋅ m = 1724 + 4219

   7273 – 5 ⋅ m = 5943

   5 ⋅ m = 7273 – 5943

   5 ⋅ m = 1330

   m = 1330 : 5

   m = 266

4. (2681 + 2 ⋅ c) – 2198 = 1409

   2681 + 2 ⋅ c = 1409 + 2198

   2681 + 2 ⋅ c = 3607

   2 ⋅ c = 3607 – 2681

   2 ⋅ c = 926

   c = 926 : 2

   c = 463

5. 19045 – (8949 + 6 ⋅ r) = 9322

   8949 + 6 ⋅ r = 19045 – 9322

   8949 + 6 ⋅ r = 9723

   6 ⋅ r = 9723 – 8949

   6 ⋅ r = 774

   r = 774 : 6

   r = 129

6. 2786 – (993 + 5 ⋅ f) = 1728

   993 + 5 ⋅ f = 2786 – 1728

   993 + 5 ⋅ f = 1058

   5 ⋅ f = 1058 – 993

   5 ⋅ f = 65

   f = 65 : 5

   f = 13

7. 3014 – (1869 + 4 ⋅ q) = 829

   1869 + 4 ⋅ q = 3014 – 829

   1869 + 4 ⋅ q = 2185

   4 ⋅ q = 2185 – 1869

   4 ⋅ q = 316

   q = 316 : 4

   q = 79

8. 25951 – (19673 + 7 ⋅ v) = 2239

   19673 + 7 ⋅ v = 25951 – 2239

   19673 + 7 ⋅ v = 23712

   7 ⋅ v = 23712 – 19673

   7 ⋅ v = 4039

   v = 4039 : 7

   v = 577

9. (2 ⋅ p – 1396) – 1839 = 5655

   2 ⋅ p – 1396 = 5655 + 1839

   2 ⋅ p – 1396 = 7494

   2 ⋅ p = 7494 + 1396

   2 ⋅ p = 8890

   p = 8890 : 2

   p = 4445

10. (8 ⋅ b – 428) – 684 = 1632

    8 ⋅ b – 428 = 1632 + 684

    8 ⋅ b – 428 = 2316

    8 ⋅ b = 2316 + 428

    8 ⋅ b = 2744

    b = 2744 : 8

    b = 343

11. (13 ⋅ n – 165) – 918 = 633

    13 ⋅ n – 165 = 633 + 918

    13 ⋅ n – 165 = 1551

    13 ⋅ n = 1551 + 165

    13 ⋅ n = 1716

    n = 1716 : 13

    n = 132

12. (4 ⋅ d – 4025) – 2338 = 1537

    4 ⋅ d – 4025 = 1537 + 2338

    4 ⋅ d – 4025 = 3875

    4 ⋅ d = 3875 + 4025

    4 ⋅ d = 7900

    d = 7900 : 4

    d = 1975

13. (3 ⋅ a – 258) – 482 = 313

    3 ⋅ a – 258 = 313 + 482

    3 ⋅ a – 258 = 795

    3 ⋅ a = 795 + 258

    3 ⋅ a = 1053

    a = 1053 : 3

    a = 351

14. 12 ⋅ k + 6767 = 7067

    12 ⋅ k = 7067 – 6767

    12 ⋅ k = 300

    k = 300 : 12

    k = 25
