Show that 3rVy((A(x) → B(y))^(C(x, y) → B(y))) is logically equivalent to ExVy(-B(y) → (¬A(x) A -C(x, y))). Make sure to cite all steps (e.g. De Morgan's law). You should neither combine steps nor skip steps. The only steps that can be combined on a single line are the associative and commutative laws."
