You do eat tuna don't you?
There has been much discussion about that particular point. I do not believe it is posted anywhere in the rules clearly. I would suggest not giving the full answer away but rather try to get the OP do it for himself. Help him along with hints and suggestions or show him a bit of math that can get the answer.
Is that an answer?
Too much notation for such a simple problem don't ya think? I thought there was a rule against just giving away the answer like that?
Give a guy a couple of fish and he's bloated for a day. Teach him how to fish and he can open a good seafood restaurant that bobbym can eat at.
Have you tested that?
Does it get all the solutions?
You are doing what he did. You know the answer before you asked the questions.
The first thing I ever taught you was to never ask a question you didn't already have the answer to. - The Verdict
The verification you showed me 2 hours ago:
That is not factual.
I didn't say that the right answer wasn't posted. I said the correct solution hadn't been posted yet.
The solution you propose is longer and requires more work.
This solution uses the defining properties of both ellipse and hyperbola. This is shorter.
It can be shortened more because you don't even need to know. He could've got that with EM. It is obvious that solving 2 linear equations is terse and therefore best.
