=#((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))#
