It still equals 1, you can prove it without using fractions: x = 0.999… 10x = 9.999… 10x = 9 + 0.999… 10x = 9 + x 9x = 9 x = 1

There’s even a Wikipedia page on the subject

I hate this because you have to subtract .99999… from 10. Which is just the same as saying 10 - .99999… = 9

Which is the whole controversy but you made it complexicated.

  You don’t subtract from 10, but from 10x0.999… I mean your statement is also true but it just proves the point further.

Do that same math, but use .5555… instead of .9999…

  Have you tried it? You get 0.555… which kinda proves the point does it not?

  Not sure what you’re aiming for. It proves that the setup works, I suppose.
  
  x = 0.555…
  
  10x = 5.555…
  
  10x = 5 + 0.555…
  
  10x = 5+x
  
  9x = 5
  
  x = 5/9
  
  5/9 = 0.555…
  
  So it shows that this approach will indeed provide a result for x that matches what x is supposed to be.
  
  Hopefully it helped?
