The sum of two numbers is 12. The difference between the square of the larger number and the square of the smaller number is 24. Find these two numbers.
Let x and y those numbers
x+y=12 (1)
x^2-y^2 = 24 (2)
From (2) (x-y)(x+y)=24
Then: (x-y)12=24
x-y = 2 (3)
Adding (1)+(3)
2x = 14
x = 7
Using (1) 7+y=12
y = 5
Answer: x = 7, y = 5
