Four different colored balls weigh different amounts. The red ball weighs the same of the combined weight of the blue and yellow balls. The lightest ball weighs as much as the green ball when a red ball is combined with the lightest ball's weight. All the balls combined weigh 20 pounds. The blue ball's weight is twice the yellow ball's weight. What is the weight of each ball?
