Решите уравнение1) x-7/12=3/42) x-1/6 = 1/93) x-3/5=3/8 решите уравнение

1) x-7/12=3/4

2) x-1/6 = 1/9

3) x-3/5=3/8

4) x-5/24=11/12

5) y-2/7=1/3

6) x-5/6=7/9

7) y-3/8=5/32

8) y-2/5=1/2

1) x-7/12=3/4

х=3/4+7/12 = (3*3+7*1) / 12

x=16/12=4/3

x=1 целая 1/3

2) x-1/6 = 1/9

х=1/9+1/6 = (1*2+1*3) / 18

x=5/18

3) x-3/5=3/8

x=3/8+3/5 = (3*5+3*8) / 40 = (15+24) / 40

x=39/40

4) x-5/24=11/12

x=11/12+5/24

x = (11*2+5*1) / 24=27/24=9/8

x=1 целая 1/8

5) y-2/7=1/3

y=1/3+2/7

y = (1*7+2*3) / 21 = 13/21

y=13/21

6) x-5/6=7/9

x=7/9+5/6 = (7*2+5*3) / 18=29/18

x=1 целая 11/18

7) y-3/8=5/32

y=5/32+3/8 = (5*1+3*4) / 32=17/32

y=17/32

8) y-2/5=1/2

y=1/2+2/5 = (1*5+2*2) / 10=9/10

y=9/10
