@SineoftheTime Gone. Another wrong answer by the same user.

@amWhy @Jakobian @JoséCarlosSantos @KReiser: Please see the above WA, which has gotten 2 ridiculous upvotes.

@XanderHenderson Hi, I have a question just closed by closing votes with just one downvote. I would like you to review if the closing is in line with MSE rules since they don't left explanation of the downvotes and the question is well explained and focused: just asked for trying a change of variable on a vectorial eqn I get stuck to solve by myself math.stackexchange.com/q/4982726/909869

@XanderHenderson In advance, thanks you very much

@user21820 It can be deleted now.

@JoséCarlosSantos Thanks! =)

@user21820 The question should be closed. All relevant content is in links to images, and the author did not improve at on request.

@user21820 Btw, the other answer tries to answer the question, as far as I can see. The answer may be wrong and you are welcome and encouraged to point out the errors. But (IMO) there is no need to refer to it as a “so-called 'answer'.” Just my 2ct.

@MartinR It's been less than a day, but up to you. Personally, I've always been lenient as long as effort is shown, which is the case here, regardless of format.

D1, D2, D3.
