Three nines is equal to 9(3).
So 9 x 3 is 27, meaning that the number should be 27+
"If you subtract nine from me" is the first phrase we can see at the problem, meaning that we should reverse and make it "if you add nine from the more than of three nines" which can be the answer.
So, 28 + 9 is 37
The full solution for this is:
9 x 3 + 1 +9
27 + 1 + 9
28 + 9
= 37
