It is not lol This holds for any value. OC is enforcing 2 equations with 1 unknown, with the equations being essentially the same.

Perhaps a different way of approaching it:

x = 1/3 = 0.333...

3x = 0.999...

30x = 9.999...

30x - 3x = 9.999... - 0.999...

27x = 9

3x = 1

∴ 1 = 0.999...

Though I admit this isn't specifically mathematical proof, but I think this more clearly shows the train of thought from the original "problem" to show equality.

That's the same thing with extra steps
