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...

math
both are right. the line does have infinite solutions, so either way works. it really depends on what you think works best or how your teacher teaches it.

yes!! to check, just plug in the numbers and see if they fit. :)

LOONDSI i tried this one. kinda. i don't think this is right but my equation was this: 6a+15=b -15 -15 6a=b-15 -b -b -15=6a-b -1(-15=6a-b) 15=(-6)a+b and then i guessed and checked... (-2,3) worked but that didn't help. now i'm stuck too. nooni

what i would do is divide 30 by 2, which is 15. then, since they are 8 apart, find 15-4 and 15+4. those are the two numbers they are 8 apart and =30. hope this helps, mel
