Question

Please help I’m very confused and if you could explain, that would be great thank you.

Answer 1

So you have (1/4)n-16
to bring out the 1/4, you have to divide 1/4 from every term.
(1/4)n/(1/4)=n
16/(1/4)=64
Thus you get (1/4)(n-64)

Answer 2

I think 1/4n-4 is the correct answer because the 1/4n is the same and 4 times 4 will equal 16
