If X=1.999999999999...

and 10x=19.999999999999...

then   10x=19.999999999999...
      -  x= 1.999999999999...
       ----------------------
        9x=18

and      x=18/9 or x=2

Therefore 2 = 1.999999999999...

True!

This is true because, as you've just proven, 1 = 0.99999999999999999....  
It's something that a lot of people have trouble accepting, but it's true.
Here's another thing to think about: if 1 and 0.999999... weren't different
numbers, there would be some numbers in between the two of them.  It'll be
pretty hard for you to find any numbers in between 1 and 0.99999..., though.
