There are 26 total marbles. We will call x the number of blue marbles. So there are x+2 red marbles. If you add them together you get x + x + 2....and all that equals 26 (subtract 2 from each side and add the two x's together) 26 - 2 = x + x 24 = 2x then divide each side by two and you get 24/2 = 2x/2 simplified is 12 = x So x is 12 (blue marbles) and x + 2 is 14 is (the amount of red marbles). 12 + 14 = 26!
