Question
Using rules of inference, laws of logical equivalences, and other definitions
taught in class, show that the hypotheses below conclude with b. Give the
reason for each step as you show that b is concluded. Each reason should
be the name of a rule of inference and include which numbered steps are
involved, For example, a reason for a step might be “Modus ponens using
#2 and #3”. (Hint: You may use the definition of biconditional and the
commutative law).
1) y ↔x
2) x ∧(b ∨¬d)
3) x ∧a →¬b
4) (¬y ∨x) ∧c →d
5) y →c
