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
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
