(45y-9xy)/(x^2y-25y)

I got an answer of 9y/y(x+5) but it seems to be wrong

Could anyone see what I did wrong. Thank you

9y(5-x)/[y(x^2-25]

[-9y(x-5)]/[y(x+5)(x-5)]

I added a negative sign in the numerator in order to make (5-x)-> -(x-5)

you can take it from.

hint: notice you can eliminate the y and (x-5)
