Решите уравнение: a) 1 - y = 7/24 + 1/4; б) 1 + m = 3/5 + 6/15; в) l + 3 5/6 = 7 1/6 - 2 2/3.

a) 1 - y = 7/24 + 1/4

1 - y = 7/24 + 6/24

1 - y = 13/24

y = 1 - 13/24

y = 24/24 - 13/24

y = 11/24

б) 1 + m = 3/5 + 6/15

1 + m = 9/15 + 6/15

1 + m = 15/15

1 + m = 1

m = 1 - 1

m = 0

в) l + 3 5/6 = 7 1/6 - 2 2/3

l + 3 5/6 = 7 1/6 - 2 4/6

l + 3 5/6 = 6 7/6 - 2 4/6

l + 3 5/6 = 4 3/6

l = 4 3/6 - 3 5/6

l = 3 9/6 - 3 5/6

l = 4/6 = 2/3
