12 and 7

Step-by-step explanation:

x + y = 19

xy = 84 OR 2xy = 168

First we have to square the first equation. That is x² + 2xy + y² = 361.

We can substitute the second equation for 2xy and we get x² + y² = 193

We can now solve for x and y which is 12 and 7.

Hope this helps!

7 and 12

Step-by-step explanation:

Define x:

Let one of the number be x

The other number is 19 - x

Solve x:

Their product is 84

x (19 - x) = 84

19x - x² = 84

x² - 19x + 84 = 0

(x - 7) (x - 12) = 0

x = 7 or x = 12

When x = 7, the other number is 19 - 7 = 12

When x = 12, the other number is 19 - 12 = 7

⇒ The numbers are 7 and 12

The numbers are 7 and 12
