Adult tickets for a play cost $11 and child tickets cost $10. If there were 23 people at a performance and the theater collected $246 from the ticket sales, how many children attended the play?

I have almost got it I think but I just cannot get there.
Is it 11x+10y=246
I know this is the equation but I get lost from there
Thank you in advance for the help!!

In honor of Martin Kruskal (http://www.latimes.com/news/science/la-me-kruskal6jan06,1,3884010.story?track=rss and http://en.wikipedia.org/wiki/Martin_Kruskal ), whose work on solitons helped create the fiber optic cable, I ask the following:

One of Kruskal's most famous contributions to mathematical literature is called the Kruskal Count, which is, of all things, a card trick. It apparently is related to Markov chains, another thing that I don't really understand.

The Kruskal Count is described in detail in the following paper:

http://arxiv.org/PS_cache/math/pdf/0110/0110143.pdf

10 points to the person who can give the best explanation of how the Kruskal Count card trick works.

(the repeating .7 is when the seven has a line above the number; it will just go on and on forever like this: .777777777777777777777777 .
and why is one bigger than the other?
