It's not if you started from x=2.

That's a variable declaration, I'm done talking about this.

There is no function.

Certainly f(x) = x is not the same as f(x) = x^2, but this isn't a function we're analyzing, so I'm tired of discussing it. It's obsolete.

All maths problems effectively start from a "variable declaration".

Like, 3x-5=0 is equivalent to a declaration that x=5/3

But if you can't see that straight away you can do a number of steps. But really everything single step is the same as saying "1=1".
