Homework Help: algebra

Posted by Rachelle on Tuesday, February 17, 2009 at 4:41pm.

5 green balls and 2 red balls together weigh 10 pounds, and 1 green ball and 4 red balls together weigh 7 pounds. If all red balls weigh the same amount and all green balls weigh the same, then what is the weight of 8 red and 8 green balls together?

I'm not sure at all how to solve this one, either... please help in any way you can! Thanks! :-)
