$\"b\"$ = number of boys
\n" ); document.write( " $\"g\"$ = number of girls
\n" ); document.write( " $\"n\"$ = number of chaperones
\n" ); document.write( " $\"b+=+2n+-+6\"$
\n" ); document.write( " $\"g+=+%28b%2F2%29+-+7\"$
\n" ); document.write( "There are only 2 equations and 3 unknowns. That means that
\n" ); document.write( "the answer has to be in terms of $\"n\"$ , $\"b\"$ or $\"g\"$
\n" ); document.write( "It looks like the problem wants it in terms of $\"n\"$
\n" ); document.write( " $\"g+=+%28%282n+-+6%29%2F2%29+-+7\"$
\n" ); document.write( " $\"g+=+n+-+3+-+7\"$
\n" ); document.write( " $\"g+=+n+-+10\"$
\n" ); document.write( "The total number of people is
\n" ); document.write( " $\"n+%2B+b+%2B+g+=+n+%2B+2n+-+6+%2B+n+-+10\"$
\n" ); document.write( " $\"n+%2B+b+%2B+g+=+4n+-+16\"$ answer \n" ); document.write( "

\n" );
