Ответ:
Решение уравнений:
- X - (151 + 32) = 74
- X + (13 + 16) = 49
- (X - 15) + 19 = 48
- 83 - (x - 11) = 43
- 21 - (x - 2) = 10
- (X - 8) + 18 = 38
- X - (12 + 16) = 76
- (X + 4) + 8 = 28
- 11 - (x + 2) = 8
- (X + 8) - 18 = 38
X - 183 = 74
X = 74 + 183
X = 257
X + 29 = 49
X = 49 - 29
X = 20
X - 15 = 48 - 19
X - 15 = 29
X = 29 + 15
X = 44
83 - x + 11 = 43
94 - x = 43
-x = 43 - 94
-x = -51
X = 51
21 - x + 2 = 10
23 - x = 10
-x = 10 - 23
-x = -13
X = 13
X - 8 = 38 - 18
X - 8 = 20
X = 20 + 8
X = 28
X - 28 = 76
X = 76 + 28
X = 104
X + 4 = 28 - 8
X + 4 = 20
X = 20 - 4
X = 16
11 - x - 2 = 8
9 - x = 8
-x = 8 - 9
-x = -1
X = 1
X + 8 = 38 + 18
X + 8 = 56
X = 56 - 8
X = 48
