10x = 9.99999..
10x - x = 9.99999.. - 0.99999..
9x = 9
x = 1
Actually its like this
x = 0.99999
10x = 9.99999
10x-x = 10(0.99999)-0.99999
=9.99999-0.99999
=1

Actually no, Peter's was the correct way of putting it.

9.99999-0.99999 doesn't = 1.
You skipped the step where you needed to put 9x = 9, and then you could simplify to x=1.

yeah...? well? I know that 1+6 = 16

Law of arithmetic equality: a=b, iff a-b=0.
And now what we have: a=1, b=0.99999.., so a-b=(0.00001..)
So, it doesn't work.

Seriously?
Epic fail.

Now read my message again and take these dots into account, I didn't include them because they look fancy.

Actually, what Peter said was, believe it or not, correct.

1=0.99 just as much as 0.13 = 13/99
The numbers 1 and 13/99 aren't infinite, but the others are.
Its just limiting infinite numbers.

This topic is giving me a headache, I'm going to stay out of it for now.
