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!
