Пошаговое объяснение:

1)

36 : (7 - 5/6х ) = 8

7 - 5/6х = 36 : 8

7 - 5/6х = 36/8

7 - 5/6х = 4. 4/8

7 - 5/6х = 4. 1/2

5/6х = 7 - 4. 1/2

5/6х = 6. 2/2 - 4. 1/2

5/6х = 2. 1/2

х = 2. 1/2 : 5/6

х = 5/2 : 5/6

х = 5/2 * 6/5

х = 6/2

х = 3

2)

27 : (5. 1/3 + 1/9х) = 4,5

5. 1/3 + 1/9х = 27 : 4,5

5. 1/3 + 1/9х = 6

1/9х = 6 - 5. 1/3

1/9х = 5. 3/3 - 5. 1/3

1/9х = 2/3

х = 2/3 : 1/9

х = 2/3 * 9/1

х = 18/3

х = 6
