Question

помогитеее пожалуйста!!!!

Answer 1

x-5/12=3/12
x=3/12+5/12
x=8/12=4/6=2/3

18/23-(7/23+y)=5/23
18/23-7/23-y=5/23
11/23-y=5/23
y=11/23-5/23
y=6/23

Answer 2

a)
x - 5/12 = 3 /12
x = 3/12 + 5/12 = (3+5)/12 = 8/12 = 2/3

ответ: x = 2/3

b)
18/23 - (7/23 +y) = 5/23
18/23 - 7/23 - y = 5/23
y = 18/23 - 7/23 - 5/23 = (18 - 7 - 5)/23 = 6/23

ответ: y = 6/23
