Пошаговое объяснение:

А

2 1/2х-1 5/8=2 3/4

2 1/2х=2 3/4+1 5/8

2 1/2х=3 11/8

х=35/8:5/2=35/8×2/5=7/4=1 3/4

Н

1/4+х: 3 5/9=7/16

х:3 5/9=7/16-1/4

х:3 5/9=3/16

х=3/16×3 5/9=3/16×32/9=2/3

Ь

4 2/5:х-2 3/5=7/10

4 2/5:х=7/10+2 3/5

22/5:х=7/10+13/5

22/5:х=33/10

х=22/5:33/10

х=22/5×10/33=4/3=1 1/3

Л

3 1/3:(2 1/8-х)=2 2/9

17/8-х=10/3:20/9

17/8-х=10/3×9/20

17/8-х=3/2

х=17/8-3/2=5/8

Е

(5/12+1/2х):2 1/2=11/12

5/12+1/2х=11/12×2 1/2

5/12+1/2х=11/12×5/2

5/12+1/2х=55/24

1/2х=55/24-5/12

1/2х=45/24

х=45/24:1/2

х=45/24×2/1=15/4=3 3/4

Ф

(6 3/14-х)×2 1/3=9 5/6

87/14-х=59/6:7/3

87/14-х=59/6×3/7

87/14-х=59/14

х=87/14-59/14

х=28/14=2

Ю

(2 1/10-х):8+1 2/15=1 1/3

(21/10-х):8=4/3-17/15

(21/10-х):8=3/15

21/10-х=3/15×8

21/10-х=24/15

х=21/10-24/15

х=63/30-48/30=15/30=1/2

Р

4 1/6:(1/4х+1 4/15)-1 5/6=2/3

25/6:(1/4х+19/15)=2/3+11/6

25/6:(1/4х+19/15)=15/6

1/4х+19/15=25/6÷15/6

1/4х+19/15=25/6×6/15

1/4х+19/15=5/3

1/4х=5/3-19/15

1/4х=6/15

х=6/15:1/4=2/5×4/1=8/5=1 3/5

Г

1 1/2х+1/2х=1 2/3

2х=5/3

х=5/3:2=5/3×1/2=5/6

П

3 4/5х-1 7/10х=3 1/2

2 1/10х=7/2

х=7/2:21/10=7/2×10/21=5/3=1 2/3

И

2/3x+7/12+1/4x+5/6=5 1/12

11/12x+17/12=61/12

11/12x=61/12-17/12

11/12x=44/12

x=44/12:11/12=44/12×12/11=4

T

3/5+4/5x+7/10x+1 1/2=5 3/5

15/10x+3/5+3/2=28/5

15/10x+21/10=28/5

15/10x=28/5-21/10

15/10x=35/10

x=35/10:15/10=35/10×10/15=7/3=2 1/3
