Why does silver carbonate dissolve in nitric acid?

[kevinnn]

This is my last question on a prefab and I want to make sure this answer is correct. The question states;
On the basis of LeChatelier's principal, explain why silver carbonate dissolves when nitric acid is added.
I said it was because mixing nitric acid and silver carbonate will produce silver nitrate, which is soluble, and carbonic acid, (I'm assuming carbon dioxide and water which forms carbonic acid). This answer seems much more like the explanation of just a chemical reaction instead of relating directly to LeChatelier's principal. What am I missing? Thanks.

You ignored the (most important) final step. What happens to carbonic acid?

Thanks.
