assume there are $\"x\"$ boys and $\"y\"$ girls\r
\n" ); document.write( "\n" ); document.write( " $\"%282%2F3%29x+%2B+%281%2F12%29y+=+385\"$
\n" ); document.write( "where $\"%282%2F3%29x\"$ represents the number of boy surfers, and $\"%281%2F12%29y\"$ represents the number of girl surfers
\n" ); document.write( "and \r
\n" ); document.write( "\n" ); document.write( " $\"2x+=+y\"$ (two girls for every boy)\r
\n" ); document.write( "\n" ); document.write( "then:\r
\n" ); document.write( "\n" ); document.write( " $\"%282%2F3%29x+%2B+%281%2F12%29%282x%29+=+385\"$
\n" ); document.write( " $\"2x%2F3+%2B+2x%2F12+=+385\"$
\n" ); document.write( " $\"8x%2F12+%2B+2x%2F12+=+385\"$
\n" ); document.write( " $\"10x%2F12+=+385\"$
\n" ); document.write( " $\"10x+=+4620\"$
\n" ); document.write( " $\"x+=+462\"$ ...number of boys
\n" ); document.write( " $\"y+=+2%2A462+=+924\"$ ...number of girls\r
