That starts out as an algebra problem with two equations in two unknowns.

x -y = 12

xy = 17

Since 17 is a prime number, x and y will not be integers. Solve by substitution.

x - 17/x = 12

x^2 -12 x -17 = 0

Once you have found out the numbers, complete the final operations. We will be happy to critique your work. You learn by trying.
