Пошаговое объяснение:

(3/8х-5/6)(9 1/6-5 2/3)=2 1/3

(3/8х-5/6)(9 1/6-5 4/6)=2 1/3

(3/8х-5/6)*3 1/2=2 1/3

3/8х-5/6=2 1/3:3 1/2=7/3*2/7

3/8х-5/6=2/3

3/8х=2/3+5/6=4/6+5/6

3/8х=9/6

Х=9/6:3/8=9/6*8/3

Х=12/3=4

(1/4х-7/12)(3/14+1/2)=5/6

(1/4х-7/12)(3/14+7/14)=5/6

(1/4х-7/12)*5/7=5/6

1/4х-7/12=5/6:5/7=5/6*7/5

1/4х-7/12=7/6

1/4х=7/6+7/12=14/12+7/12

1/4х=21/12=7/4

Х=7/4:1/4=7/4*4

Х=7
