Homework Statement
∃x∀y(y̸=0→xy=1) in the real numbers universe.
Homework Equations
The Attempt at a Solution
Since the given statement is false I negated the whole statement to become
∀x∃y(y̸!=0^xy!=1) (!= means not equal to)
then I would have to prove this correct by setting y to something except zero
I can't find any y to prove this correct
