Пошаговое объяснение:
10) 67 - 36 : x = 55
-36 : x = 55 - 67
-36 : x = -12
x = -36 : (-12)
x = 3
11) 8 * (x - 7) = 1080
x - 7 = 1080 : 8
x - 7 = 135
x = 135 + 7
x = 142
12) (k + 11) : 23 = 27
k + 11 = 27 * 23
k + 11 = 621
k = 621 - 11
k = 610
13) 900 : (210 - x) = 36
210 - x = 900 : 36
210 - x = 25
х = 210 - 25
х = 185
14) 124 : (3x + 4) = 4
3x + 4 = 4 * 124
3x + 4 = 496
3x = 496 - 4
3x = 492
x = 164
15) 63 : (2x - 1) = 7
2x - 1 = 7 * 63
2x - 1 = 441
2x = 442
x = 221
16) 248 : (41 - 2x) = 8
41 - 2x = 248 : 8
41 - 2x = 31
2х = 41 - 31
2х = 10
x = 5
17) 18 * (7x + 26) = 1854
7x + 26 = 1854 : 18
7x + 26 = 103
7x = 77
x = 11
18) (5x+1) : 16 = 6
5x + 1 = 16 * 6
5x + 1 = 96
5x = 95
x = 19
19) (483 - 8x) : 43 = 9
483 - 8x = 9 * 43
483 - 8x = 387
-8x = 387 - 483
-8x = -96
x = 12
20) 21 * (5x +14) = 2499
5x + 14 = 2499 : 21
5x + 14 = 119
5x = 119 - 14
5x = 105
x = 105 : 5
x = 21
