Пошаговое объяснение:

720 : (5x - 12) - 56 = 34

720 : (5x - 12) = 34+56

720 : (5x - 12) = 90

5x - 12 = 720 : 90

5x - 12 = 8

5x = 8+12

5x = 20

x = 20:5

x = 4

==================

92 + 56 : (14 - b) = 100

56 : (14 - b) = 100 - 92

56 : (14 - b) = 8

14 - b = 56 : 8

14 - b = 7

b = 14 - 7

b = 7

==================

39 - (15z + 48) : 27 = 35

(15z + 48) : 27 = 39 - 35

(15z + 48) : 27 = 4

15z + 48 = 4 * 27

15z + 48 = 108

15z = 108 - 48

15z = 60

z = 60 : 15

z = 4

==================

56 - (x + 12) = 24

x + 12 = 56 - 24

x + 12 = 32

x = 32 - 12

x = 20

====================

144 - y - 54 = 37

90 - y = 37

y = 90 - 37

y = 53

================
