? Where did you get 9x=5 -> x=1 and 5/9 is 0.555… so it checks out.
Comment on I just cited myself.

10x=5.5555…
Subtract x from both sides.
9x=5
X=1 .5555 must equal 1.
There it isn’t. Because that math is bullshit.

Lol what? How did you conclude that if
9x = 5
thenx = 1
? Surely you didn’t pass algebra in high school, otherwise you could see that gettingx
from9x = 5
requires dividing both sides by 9, which yieldsx = 5/9
, i.e.0.555… = 5/9
.

x = 5/9 is not 9/9. 5/9 = .55555…
You’re proving that 0.555… equals 5/9 (which it does), not that it equals 1 (which it doesn’t).
It’s absolutely not the same result as x = 0.999… as you claim.
