Prove if a/b and a/c then a/(b+C)

let a,b,c (element of) (integers.)

I'm sure there's a genius that can figure this out.

Thanks!!

More intuitively, if $a$ divides both $b$ and $c$, that means that $b$ and $c$ are both multiples of $a$ (by definition). So their sum must also be a multiple of $a$, and the result follows.[/JUSTIFY]
