Assume that the domain is nonempty. a) ∀x(A → P(x)) ≡ A → ∀xP(x) b) ∃x(A → P(x)) ≡ A → ∃xP(x) My Solution. a) Suppose A is false. Then A -> P(x) is trivially true because if hypothesis is false then conditional statement is trivially true. hence, both left …

First would be "someone has internet" exists X. I (x) and second would be "if two people have internet then they are the same person" forall x,y. I (x) and I (y) -> x = y.
