+118703 I ususally use the sensible guess method too saseflower but here is another way.
What two factors of 1080 equal the sum of 69
xy=1080 (1)
x+y=69 so y=69-x (2)
sub 2 into 1
x(69−x)=108069x−x2=10800=x2−69x+1080$nowyoucansolveitwiththequadraticformula$
x2−69×x+1080=0⇒{x=45x=24}
+1975 Well first guess and check
I just subtracted random numbers from 69 and then multiplyed them with the difference.
I finally got 45 and 24
Basically you just have to do guess and check
