Answer 2

Answer:

The numbers are 7 and 9.

Step-by-step explanation:

Let's assume that, one of the numbers is x.

According to the problem, the other number is (16 - x)

And $x(16 - x) = 63$

$=>16x - x^2 = 63$

$=>x^2 - 16x + 63 = 0$

$=>x^2 - 7x - 9x + 63 = 0$

$=>x(x - 7) - 9(x - 7) = 0$

$=>(x - 7)(x - 9) = 0$

∴ x = 7, and 16 - x = 9

or, x = 9, and 16 - x = 7

∴ the numbers are 7 and 9.
