You can cancel a '4' and a 'y' out of this expression, but that's all
Explanation:
Note that each term in the expression, both in the numerator and the denominator has a 4 in it. So, since 4/4 = 1, we can cancel those:
Then, each term also has a 'y' in it, so we can cancel those also since y/y = 1
That's all we can do since there is nothing else that is common to every term
