Number Pattern Question 7 by Kiang Jia Ming Kenneth

Part D was the difficult question as I was trying to find a solution that does not require trial and error. I filled the original piece with workings trying to solve it and kept trying different ways to manipulate x and y. In the end I realised that the square root of multiplying both of them together must be in between both of the numbers, and I can find out the exact numbers since one number is just larger than the other by 1.
