Answer:
y = 8 and x = 7
Step-by-step explanation:
I cant explain but here is what I did :
Squares are basically the consecutive sum of odd numbers i.e. if you add consecutive odd numbers , you will pretty surely obtain a square number . And since 15 cant be the sum of any two odd numbers , x and y had to be consecutive numbers . So , I did a bit of math and found out that the difference of squares of any two consecutive numbers is the sum of those two consecutive numbers i.e. if x and y are two consecutive numbers , x^2 - y^2 = x + y
I solved for x and y and I obtained the answer
