Ответ:

Решим уравнения:

x + 23 = 93 - 53
x + 23 = 40
x = 40 - 23
x = 17
x - 37 = 48 + 15
x - 37 = 63
x = 63 + 37
x = 100
19 + x = 37 + 18
19 + x = 55
x = 55 - 19
x = 36
51 - x = 86 - 52
51 - x = 34
x = 51 - 34
x = 17
34 + x = 91 - 28
34 + x = 63
x = 63 - 34
x = 29
x - 20 = 63 - 14
x - 20 = 49
x = 49 + 20
x = 69
x + 56 = 27 + 60
x + 56 = 87
x = 87 - 56
x = 31
x * 10 = 30 : 3
x * 10 = 10
x = 10 : 10
x = 1
x * 9 = 6 * 3
x * 9 = 18
x = 18 : 9
x = 2
56 : x = 72 : 9
56 : x = 8
x = 56 : 8
x = 7
5 * x = 80 : 8
5 * x = 10
x = 10 : 5
x = 2
x * 4 = 2 * 8
x * 4 = 16
x = 16 : 4
x = 4
54 : x = 3 * 3
54 : x = 9
x = 54 : 9
x = 6
x : 6 = 2 * 3
x : 6 = 6
x = 6 * 6
x = 36
