OK, wait a minute I'll edit this post.
Edit: Juan has x coins in the beginning and if he gives 3 coins to Luisa, after that he'll have "n" times as many coins as her at that moment.
Luisa had y coins in the beginning and after this, she would have y+3. That's why I wrote:
x-3=n·(y+3)
However Luisa replies that if Juan (in the beginning) had given her "n" coins, she would have 3 times as many coins as Juan after this. So:
y+n=3·(x-n)
That's why I wrote this:
I have more steps done apart from that one, but still it doesn't lead me to a solution.
The original in Spanish: Juan le dice a Luisa: Si me das 3 monedas yo tendré n veces las que tú tengas. Ya le responde Luisa: pero si tú me das a mí n monedas, entonces tendré el triple de las que te quedan a ti. ¿Para qué valores de n son verdaderas estas afirmaciones?
Just in case don't quote that (the problem in Spanish). I wouldn't like my mum finding out that I post coments on a forum and I go there asking for help in Math

but that's so weird, because then there are 2 equation with 3 unknowns. Is that image from your book, like do they really expect you to solve those? And what is that arrow about? I feel like there's something missing.

Btw let my earlier dumb blunders be a nice cautionary tale to actually read the problem carefully before you just start solving

I think I'm gonna create Music Banter's Official Math Thread ask all my questions there and post a problem per week.

excellent, go for it.

I'm still bothered by this problem though, because it shouldn't be solvable this way. The fact that all unknowns are integers reduces the number of solutions, but still it's not enough. Is that picture really the complete problem you have to solve? Is there any other context?

^There's more here.
I have to solve the problem in an online document and send it to the Math (or is it Maths?) teachers of our high school. So that was just a screenshot of what I had written. The problem is I gotta send it TONGIHT. So I have like 2 hours or so.

Hello again!
I'm finally able to listen to music again! It's been such a hard time. I mean, doing homework without listening to music, that's the worst psychological torture I've ever experienced.
So, I'm going to continue listening to your suggestions.
Thanks and cheers!

Yay! She's back! Hope your ear is all healed up now. Welcome back, you were missed.

Here's another proggy rec to get you right on your way...

(Edison's Children is a side-project of Pete Trewavas from Marillion)

Welcome back! Glad you can jam out again.

A few recs-

YATTE - Cool new group out of Austin, TX. Music sounds like a cross between early 80's Genesis and INXS with a modern twist.



Saga - another classic 80's group with an extensive discography. You mentioned before that you dug ELO, Alan Parsons Project, etc. so these guys fit right into that general area.
