Find two numbers whose product is 22 and whose sum is 13.
aleksandrvk [35]

Answer:

2 and 11

Step-by-step explanation:

Let's start by calling these two numbers x and y. Now, you can set up the following system of equations:

x*y=22

x+y=13

You can rearrange the following equation to be x=13-y, and substitute into the first.

(13-y)*y=22

-y^2+13y=22

y^2-13y+22=0

y=2 or 11

x=11 or 2

Hope this helps!
