15 + (y – 25) = 86;

70 – (z + 3) = 36;

18 + (56 – х) = 36;

(х + 2) ∙ 8 = 96;

(y – 12) : 7 = 9;

104 : (26 – х) = 4

Answer 1

Ответ:

Пошаговое объяснение:

15 + (y – 25) = 86;

15 + y - 25 = 86

-10 + y = 86

y = 86 + 10

y = 96

70 – (z + 3) = 36;

70 - z - 3 = 36

67 - z = 36

z = 67 - 36

z = 31

18 + (56 – х) = 36;

18 + 56 - x = 36

74 - x = 36

x = 74 - 36

x = 38

(х + 2) ∙ 8 = 96;

x + 2 = 96 : 8

x + 2 = 12

x = 12 - 2

x = 10

(y – 12) : 7 = 9;

y - 12 = 9 * 7

y - 12 = 63

y = 63 + 12

y = 75

104 : (26 – х) = 4

26 - x = 104 : 4

26 - x = 26

x = 26 - 26

x = 0
