Пошаговое объяснение:

1)

(8/15 + 2/9х) : 3/5 = 2

8/15 + 2/9х = 2 * 3/5

8/15 + 2/9х = 6/5

2/9х = 6/5 - 8/15

2/9х = 18/15 - 8/15

2/9х = 10/15

х = 10/15 : 2/9

х = 10/15 * 9/2

х = 5/5 * 3/1

х = 15/5

х = 3

2)

(7/18 + 5/24у) : 3 2/3 = 1/3

7/18 + 5/24у = 1/3 * 3 2/3

7/18 + 5/24у = 1/3 * 11/3

7/18 + 5/24у = 11/9

5/24у = 11/9 - 7/18

5/24у = 22/18 - 7/18

5/24у = 15/18

у = 15/18 : 5/24

у = 15/18 * 24/5

у = 3/3 * 4/1

у = 12/3

у = 4
