Question

Мне срочно нужна .как решит?

Answer 1

х + 7 * 4 = 40

х + 28 = 40

х = 40 - 28

х = 12

_________________

6 * 3 + х = 72

18 + х = 72

х = 72 - 18

х = 54

_________________

80 - х = 9 * 5

80 - х = 45

х = 80 - 45

х = 35

_________________

12 + х = 5 * 8

12 + х = 40

х = 40 - 12

х = 28

__________________

х - 32 : 4 = 50

х - 8 = 50

х = 50 + 8

х = 58

_________________

х + 2 * 6 = 94

х + 12 = 94

х = 94 - 12

х = 82
