Question

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

Answer 1

5у-4 2/7(2 1/3у+1 1/6)=3 1/3
5у-30/7(7/3у+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(1/3-3х)+5/8(1/3-3х)=1
19/8(1/3-3х)+5/8(1/3-3х)=1
19/24-57/8х+5/24-15/8х=1
-57/8х-15/8х=1-5/24-19/24
-72/8х=1-24/24
-9х=0
х=0
