Answer 1

Если d = 15:

58 - 15 + 20 = 63

60 + 15 - 28 = 47

(30 + 12) - 15 = 42 - 15 = 17

Если b = 10:

58 - 10 + 20 = 68

60 + 10 - 28 = 42

(30 + 12) - 10 = 42 - 10 = 32

Если b = 25:

58 - 25 + 20 = 53

60 + 25 - 28 = 57

(30 + 12) - 25 = 42 - 25 = 17

Если b = 8:

58 - 8 + 20 = 70

60 + 8 - 28 = 40

(30 + 12) - 8 = 42 - 8 = 34
