You can put this solution on YOUR website!
b = number of boys
g = number of girls
n = number of chaperones
b+=+2n+-+6
g+=+%28b%2F2%29+-+7
There are only 2 equations and 3 unknowns. That means that
the answer has to be in terms of n, b or g
It looks like the problem wants it in terms of n
g+=+%28%282n+-+6%29%2F2%29+-+7
g+=+n+-+3+-+7
g+=+n+-+10
The total number of people is
n+%2B+b+%2B+g+=+n+%2B+2n+-+6+%2B+n+-+10
n+%2B+b+%2B+g+=+4n+-+16 answer
