Пошаговое объяснение:

67 - 36 : x = 55

36 : x = 67 - 55

36 : x = 12

x = 36 : 12

x = 3

----------------

24:(x + 2) = 60 : 15

24 : (x + 2) = 4

x + 2 = 24 : 4

x + 2 = 6

x = 6 - 2

x = 4

-----------------

17 + 6(x - 5) = 47

6(x - 5) = 47-17

6x - 30=30

6x = 30+30

6x= 60

x = 60:6

x = 10

-----------------

40 - 3(x+2) = 10

3(x + 2) = 40 - 10

3x + 6 = 30

3x = 30 - 6

3x = 24

x = 24:3

x = 8

-------------------

2(x - 12) + 19 = 19

2(x - 12) = 19-19

2x - 24 = 0

2x = 24

x = 24:2

x = 12

----------------------

63 : (2x - 1) = 21 : 3

63 : (2x - 1) = 7

2x - 1 = 63 : 7

2x - 1 = 9

2x = 9+1

2x = 10

x = 10:2

x = 5

--------------------

248 : (41 - 2x) = 8

41 - 2x = 248 : 8

41 - 2x = 31

2x = 41 - 31

2x = 10

x = 10:2

x = 5

----------------

18(7x + 26) = 1854

7x + 26 = 1854 : 18

7x + 26 = 103

7x = 103 - 26

7x = 77

x = 77:7

x = 11
