Question

Реши уравнения:
55−(45+x)=5
(x−85)−24=8
95−(54+x)=8
(x−59)−25=6

Answer 1

55 - (45 + х) = 5

55 - 45 - х = 5

10 - х = 5

-х = 5 - 10

-х = -5

х = 5

(х - 85) - 24 = 8

х - 85 - 24 = 8

х = 8 + 85 + 24

х = 117

95 - (54 + х) = 8

95 - 54 - х = 8

41 - х = 8

-х = 8 - 41

-х = -33

х = 33

(х - 59) - 25 = 6

х - 59 - 25 = 6

х = 6 + 59 + 25

х = 90
