Question

Решите уравнения:
a)11/38 - y =3/38 + 5/38
b)24/31 + a - 7/31 = 22/31

Answer 1

11/38 - y = 3/38 + 5/38
11/38 - y = 8/38
y = 11/38 - 8/38
y = 3/38
------------
24/31 + a - 7/31 = 22/31
17/31 + a = 22/31
a = 22/31 - 17/31
a = 5/31

Answer 2

1) 11/38-у=3/38+5/38
    -у=3/38+5/38-11/38
    -у=-3/38
    у=3/38
2) 24/31+а-7/31=22/31
    а=22/31+7/31-24/31
    а=5/31
