...no.
Because you did not define z.
Also, to state that a value can be infinite, you would not say "x = x", you would say "-∞ < x < ∞".

Yes...
I defined what value z was, which was anything...
And I tried explaining that x is x...

Like I said, any programming language in the world (all of which heavily rely on math and algebra!) would error at you for trying to state "x = x". It tells you nothing any more than "blahbdeschninky = blahbdeschninky" or "Bob's Age = Bob's Age".

The value of z does exist and so does x.
This topic was harder than I thought. o_O

And Bob's Age exists, and (presumably) so does Blahbdeschninky.

x + y = z is only true when z is meant to be a resulting variable or, when z is defined, x and y actually add up to equal z.

x = 2
y = 3
x + y = 5
Is that what you mean?

What's wrong with the first part?
