3rd grade math (not algebra!)
from the information above: I blue = yellow + 4 II yellow = green - 2 OR yellow +2 = green and we know that III yellow + blue + green = 18 now insert upper expressions into the III equation: yellow + (yellow +4) + (yellow +2) = 18 3 yellow + 6 = 18 --> yellow = 4 insert 4 ...
