1 = 0.9... + ( 1 - 0.9...)

1 - 0.9... = x

1 = 0.9... + x

I don't see how this is reconcilable. The absence of an answer is not an answer.

In OP, wouldn't 9x = 8.9... not 9?

I'm not sure if you want us to answer that equation or what. But x would equal (1 - 0.9...) which is 0.0000... which is 0. meaning 1 = 0.9....

Yes, 9x can equal 8.9999... and 9. This works because 8.999..... is equal to 8 + 0.99999 which is also 8 + 1. 

Wouldn't it actually have to be repeating y and not repeating zero? I would consider it repeating zero but the actual quantity trying to be subtracted from one is not definitive.
