.3333.... equals to

I just show how .999.... = 1



Let x = .999....

10x = 9.999...

10x - x = 9.999... - .999...

9x = 9

x=1



So according to the above .3333.... shows as 3.



Let x = .3333...

10x = 3.333...

10x - x = 3.333... - .333...

9x = 3

x=3



But according to me, .333.... should equal to .4 , isn't it?



I must be...
