Bezout's lemma (number theory) (Theorem)

Let $ a,b$ be integers, not both zero. Then there exist two integers $ x,y$ such that:

$\displaystyle ax+by=\gcd(a,b).$
This does not only work on $ \mathbb{Z}$ but on every integral domain where an Euclidean valuation has been defined.

Bezout's lemma? by NeuRet on 2002-05-27 16:46:52
I have always known this entry as the Euclidean
algorithm. Not that I want to be greedy, but shouldn't this result go directly under the Euclidean algorithm, and in that entry, perhaps, mention this alternative name for it?
