There are 10 marbles in a bag, there are 2 times as many green marbles at there are yellow.How many green marbles and how many yellow marbles.
----------------------
Equations:
g + y = 10 marbles
g = 2y
-------------
Substitute for "g" and solve for "y":
2y + y = 10
3y = 10
y = 3 1/3 (# of yellow marbles)
------------------
Comment: The answer does not make much sense
as you cannot have 1/3 of a yellow marble.
