Answer 1

Пошаговое объяснение:

№23

2/3h + 1/2h - 3/4 = 2 - 1/3h + 2 1/4h

8/12h + 6/12h - 3/4 = 2 - 4/12h + 2 3/12h

14/12h - 3/4 = 2 - 4/12h + 1 15/12h

1 2/12h - 3/4 = 2 + 1 11/12h

1 2/12h - 1 11/12h = 2 + 3/4

-9/12h = 2 3/4

-3/4h = 11/4

h = 11/4 : (-3/4)

h = 11/4 * (-4/3)

h = 11/1 * (-1/3)

h = -11/3

h = -3 2/3

№24

1 - 1 1/2x + 3 2/5х = 1 1/3х - 2 7/15х + 2,5

1 - 1 15/30х + 3 12/30х = 1 10/30х - 2 14/30х + 2 1/2

1 - 1 15/30х + 2 42/30х = -1 4/30х + 2 1/2

1 + 1 27/30х = -1 4/30х + 2 1/2

1 27/30х + 1 4/30х = 2 1/2 - 1

2 31/30х = 1 1/2

3 1/30х = 1 1/2

91/30х = 3/2

х = 3/2 : 91/30

х = 3/2 * 30/91

х = 3/1 * 15/91

х = 45/91

№25

2*(2/5z + 1) + 3 1/3 = 4 - 1/2*(4/5z - 1)

4/5z + 2 + 3 1/3 = 4 - 4/10z + 1/2

4/5z + 5 1/3 = 4 1/2 - 2/5z

4/5z + 2/5z = 4 1/2 - 5 1/3

6/5z = 9/2 - 16/3

6/5z = 27/6 - 32/6

6/5z = -5/6

z = -5/6 : 6/5

z = -5/6 * 5/6

z = -25/36
