I'm posting this as an answer -- even though this question itself is a duplicate -- because I've answered an equivalent question before in a comment and I can't find it.
If the question is clearly well thought out and contains a usable MWE, I may vote to close it as a duplicate, but also post a straightforward "complimentary" answer to get the OP going. This is my recommended practice.
It's quite true that answers given for the question marked as a duplicate are often a bit "obscure" to a newbie, or even require rather a lot of untangling by someone with more experience, while not being amenable to updating, as that could make them inapplicable to the question they originally answered. Perhaps a new answer could be added to that question, giving information that is more easily tied to the question marked as duplicate; however, such an answer is likely to be marked as not relevant to the question it's associated with, and closed. It's evident that the format of this forum is lacking in some respects.
Here's the situation here in meta: If a query is entered for the word "duplicate", the response is over 400 entries, where the reason for some being recognized is actually closure as duplicate. If the search is for the tag "[duplicates]", the count is only 66. So at least some of the questions found by the word search and are legitimately about duplicate questions are not tagged as such; this is confirmed by reviewing the questions themselves. I'm tempted, when time permits and I'm looking for something to do, to go back through these questions and add a [duplicates] tag where appropriate.
