    The statement is true, as follows.

    [~P v (~P v X)] v (~P v A). Then substitute:

    [~P v (~P v false)] v (~P v true): Then substitute, based on anything OR'd with true is true.

    [~P v (~P v false)] v true: Then, once again, substitute, based on anything OR'd with true is true.

    true
