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

      ???

      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?
