the sum of two digits number is 7 and their product is 12. what is the difference between these two digits? how?
+118724 the sum of two digits number is 7 and their product is 12. what is the difference between these two digits? how?
You can do this formally if you want.
x+y=7
xy=12
Then solve simultaneously.
But this one is really easy.
If the 2 numbers mult to a positive then they both must be neg or both positive.
They add to a positive so they both must be positive.
3 and 4 is the obvious answer. :)
the difference between these two is 4-3=1
