X=.5555...
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.
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.
?
Where did you get 9x=5 -> x=1
and 5/9 is 0.555... so it checks out.
Quick maffs
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
sincex = 0.555...
.Also, you shouldn't just use uppercase
X
in place of lowercasex
or vice versa. Case is usually significant for variable names.
