Hi all,

I have a simple algebra problem that has been bugging me

"....the product of two numbers is 30. Their average is 6. What are the two number?"

I know this problem is easy; but, I cant seem to work it out.

I pretty much started out like this :

(a) let's say the numbers are X and Y

(b) so, average is 6. Meaning : (x+y) / 2 = 6

(c) Hence, x+y = 12

(d) Product : x * y = 30

(e) So : (x+y=12) and (x*y=30)

(f) Next, I decided to equate both expressions :

10(x+y) = 120

4(x*y) = 120

(g) So : 10(x+y) = 4xy

And, this is where I got stumped
