You can put this solution on YOUR website!
r+g+b+p=135
r=3g
b=2g
3g+g+2g+p=135
6g+p=135
(g-12)*3=p
p=3g-36
So 3g+g-12+2g+3g-36=123, putting all the other color numbers in terms of number of green balloons.
9g-48=123
9g=171
g=19 green balloons
57 red balloons
38 green balloons, and to make 135
21 purple balloons.
When 12 green balloons burst, there were 7 left, 1/3 of the 21 purple balloons
Answer is originally 19 green balloons and 21 purple balloons.
