# Put tags over several parts of an equation, that are consistent with eq numbering and can be referenced in text [closed]

Is it possible to put a tag (and a corresponding label) for a part of an equation over a brace, and another tag for a different part of the same equation over another brace? Something like this:

The tag(label) numbering should continue the numbering of the equation counter, and should be referenced later in the text.

I'm sorry if this was already answered, but I haven't managed to find such a question.

• @tex_newbee -- please add to your question the information that you would like these labels to (1) use the same counter as your other equation labels, and (2) be referenceable elsewhere in your document. if i had time to experiment (which i don't), i would try this: set a hyperref anchor for each, use \stepcounter with the usual equation counter, and \tagform to format it in a $...$ or equatino* environment. i'd assume basing this on amsmath, and would have to dig into the amsmath code for details.
