The solution to the new question math.stackexchange.com/q/5019320/42969 is a part of my answer math.stackexchange.com/a/2681485/42969 to a different older question. I would appreciate some advice what to do:
Close the new question as a duplicate? Probably not, because it is a different question.
Post a new answer with just a link to the old answer?
Post a new answer and repeat the relevant part of the old answer?
