Question

Quick Question: What are the steps in solving for Y for this equation: X=720+140y/y ?

thanks so much!

Answer 1

140y/y = 140 ?

Answer 2

The answer is Y = 720/x-140 , but I don't know how to get to that answer.

Answer 3

multiply both sides by y... to remove the denominator in the fraction

\[Xy = 720 + 140y\]

next subtract 140y from both sides

\[Xy - 140y = 720\]

take the common factor out on the left hand side

\[y(X - 140) = 720\]

hope this helps..

Thank you so much!! Been racking my brain for the last half hour!
