Q: How can I delete an Apple ID account? I exigently have two.

You can't combine Apple IDs into one.  You just stop using the one you don't need anymore.

From "Frequently asked questions about Apple ID"

I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?

Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

If you are wondering how using multiple Apple IDs relate to iCloud, see Apple IDs and iCloud.
