One of the following general laws is true, the other false. Prove the true one. Find a counter example to the other.(We must do this in writing out each statement, no truth tables or anything.
(a) If X implies Y, then the disjunction of X or Y is equivalent to X.
(b) If X implies Y, then the disjunction of X or Y is equivalent to Y.
I don't know, could you help me write out each step to prove/disprove?
