However, it's important to consider context. It might sound a bit informal in some situations.
Here are some examples:
Correct:
* You and Tracy are invited to the party.
* I saw you and Tracy at the mall.
More formal alternatives:
* Tracy and you are invited to the party.
* Ms. Jones and you are invited to the party.
Overall, "you and Tracy" is grammatically correct, but you might want to consider using a more formal alternative depending on the situation.
