What I would have done were I in your position (7,6)

'what i' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'would have done were i in your position' is the wordplay.
I cannot quite see how this works, but
'would' could be 'd' (I've seen this in other clues) and 'd' is present in the answer.
'position' could be 'place' (synonyms) and 'place' is located in the answer.
The remaining letters 'changes' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
