Four positive integers [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] have a product of [unparseable or potentially dangerous latex formula] and satisfy
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
What is [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
should i move on to easy AIME problems? or more AMC 12?

I know you all moved to AIME questions already but this one was never completely solved:
By using SFFT:
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
On the last two equations we see that they have [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] in common so we assume:
[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
By plugging this value back in to the equations we find [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula]. Finally we go back to the first equation [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]
So...
[unparseable or potentially dangerous latex formula]

go roel way to own the problem...if someone wants to go back to the simple and boring AMC 12
you have two choices
a) cry
b) go to aops and c/p them yourself
