Решите первые три уравнения. 24

Пошаговое объяснение:

1)

29/14 - 5/3х = 26/21

5/3х = 29/14 - 26/21

5/3х = 87/42 - 52/42

5/3х = 35/42

5/3х = 5/6

х = 5/6 : 5/3

х = 5/6 * 3/5

х = 1/2

2)

(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

2/9х = 2/3

х = 2/3 : 2/9

х = 2/3 * 9/2

х = 3

3)

2/5х + 3/10х - 2/15х = 1/6

12/30х + 9/30х - 4/30х = 1/6

17/30х = 1/6

х = 1/6 : 17/30

х = 1/6 * 30/17

х = 5/17
