y=0,bar(3)

Explanation:

(9y)/14=9/14-3/7

(9y)/cancel(14)=((7*9)-(3*14))/(cancel(14)*7)

y=((7*9)-(3*14))/(9*7)
y=(63-42)/63
y=0,bar(3)

y = 1/3

Explanation:

(9y)/14 + 3/7 = 9/14

Firstly change all denominators to 14 g
giving
(9y)/14 +6/14 = 9/14
Now you can ignore the denominators to get
9y + 6 = 9
Subtract 6 from both sides
9y = 3
Divide both sides by 9
y = 3/9
which simplifies to
y = 1/3
