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 into upper equation and you will get

blue= 4+4

green= 4+2
