1. ((∀x-Fx v ∀xGx) v -(∀xKx → -∃y∀z∃w-Dyzw)) & ((∀xFx & ∀x-Gx) v (∃xKx → ∀y∃z∀wDyzw))

├ ∀x(((Fx → Gx) → (Kx → ∀y∃z∀wDyzw)) & ((∃y∀z∃w-Dyzw → -Kx) → (-Gx → -Fx)))

2. -∃x(Px → ∀yGxy) v ∃x(Lx & Sx), -∀x(-Lx v –Sx) → (∀x∃y-Gxy→∃x-Px)

├ - ( ((∃x-Px v ∃x∀yGxy) → -∀x(Lx → -Sx)) → ( ∃x (Sx & Lx) & ∀x(Px & ∃y-Gxy) ) )

1. - ((H→ (-L→-P)) → - ( - (P→L) v H)) ├ (P→ (-L→ -H)) & (-P v (-H v L))
