Question

3/7-1/4y=1/2
(Those are fractions by the way)

Answer 1

First we Subtract.
`\\ (3*4)/(7*4)=\boxed{ (12)/(28)} \ and \ (1*7)/(4*7)=\boxed{ \frac{7} {28}}. Subtract:[tex] \\ (12)/(28)- (7)/(28)=\boxed{ (5)/(28)}` Now we have 5/28y=1/2. Subtract both sides from 1/2.
`\\ (5*1)/(8*1)=\boxed{ (8)/(1)} \ and \ (1*4)/(2*4)=\boxed{ (4)/(8)}` y=
`(4)/(8)`
