Trina has 36 marbles in three different colors. There are twice as many red ones as blue ones. There is one more green marble than there are red marbles. How many red marbles are there? How many green marbles are there?
Answered by Sams
It would be 14 red and 15 green

r + b + g = 36

r = 2b ... b = 1/2 r

r + 1 = g

substituting ... r + (1/2 r) + (r + 1) = 36

5/2 r = 35
