What 2 numbers multiply up to 60 but add up to 66?

Let's denote the two numbers as x and y. We know that xy = 60 and x + y = 66. By solving these two equations simultaneously, we can find that the two numbers are 6 and 10. This is because 6 * 10 = 60 and 6 + 10 = 16, which satisfies both conditions.
