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
