=((y+9))/((y-4))

Explanation:

Although we have a fraction, we MAY NOT CANCEL, because there are + and - signs in the numerator and denominator indicating that there are terms, rather than factors.

Factor the numerator and denominator first.

((y+9)(y-1))/((y-4)(y-1)) " now we have factors"

((y+9)cancel(y-1))/((y-4)cancel(y-1))

=((y+9))/((y-4))
