Let x = 0.999.... then 10x = 9.999... and subtracting gives

10x - x = 9.999... - 0.999...

So 9x = 9

You can argue as much as you want about possible solutions of 9x = 9, but in any reasonable number system (field) x = 1 is a solution (by definition of identity).

Hence, x = 0.999... = 1

You can't do maths by a poll, logic isn't governed by democracy!
