Question

(5+y)/(5-y)=3 solve for y

Answer 1

5 + y/5-y = 3
5 +y/5-y x 5-y = 3(5-y)
5 + y = 15 - 3y
5 + y -5 = 15 -3y -5
y = 10 - 3y
y + 3y = 10
4y = 10
y = 2.5
sorry i don't know for sure, but i think this is what it is.

Answer 2

well first off look at the denominator and see what y can't be.

it can't be 5 as this would result in a zero denominator


so multiply both sides by ( 5 - y)

and you get

5 + y = 3(5 - y)

distribute then collect like terms and you can then solve for y

hope this helps

Answer 3
