Answer 2

\[\frac{ 7xy }{ x }+\frac{ 10y^2 }{ 5y } = 7y + 2y = 9\]

That is a very simple function. You can solve it by yoursef. Just try a little bit. It is solved like this:
x's in the first term cancels each other(7y), y's in the second term cancels each other(10y/5). 10y/5 = 2y
7y+2y = 9y

Answer 3

can give you one more?
