Решите уравнение: 5y-4 2/7 (2 1/3y+1 1/6) = 3 1/3;

2 3/8 (1/3-3x) + 5/8 (1/3-3x) = 1

5 у-4 2/7 (2 1/3 у+1 1/6) = 3 1/3

5 у-30/7 (7/3 у+7/6) = 10/3

5y-10y-5=10/3

5y-10y=10/3+5

-5y=25/3

y=-5/3=-1 2/3

2 3/8 (1/3-3 х) + 5/8 (1/3-3 х) = 1

19/8 (1/3-3 х) + 5/8 (1/3-3 х) = 1

19/24-57/8 х+5/24-15/8 х=1

-57/8 х-15/8 х=1-5/24-19/24

-72/8 х=1-24/24

-9 х=0

х=0
