8. Dai is comparing how many trading cards he has with his friend Maura. Initially, they find that Dai has four


more cards than twice the number that Maura has.


(a) If the number of cards Maura initially has is represented by n, then write an expression for the number of


cards that Dai initially has.


(b) If Dai must give Maura 8 cards so that they have the same amount, set up and solve an equation to


determine the number of cards Maura initially had.
