Пошаговое объяснение:

1. x + 7*4 =40

x + 28 = 40

x = 40 - 28

x = 12

2. 6*3 + x = 72

x + 18 = 72

x = 72 - 18

x = 54

3. 80 - x = 9*5

80 - x = 45

x = 80 - 45

x = 35

4. 12 + x = 5*8

12 + x = 40

x = 40 - 12

x = 28

5. x - 32:4 = 50

x - 8 = 50

x = 50 + 8

x = 58

6. x + 2*6 = 94

x + 12 = 94

x = 94 - 12

x = 82
