I know sum means addition, but what does coefficient supposed to mean in this problem? Would doing 4x+4y be a step in the right direction? I am expected to know this for the upcoming quiz, and any help on this will be very much appreciated. My problem is not knowing what it is asking exactly.\r<BR>\n" );
