# of Adult tickets = $\"a\"$
\n" ); document.write( "# of student tickets = $\"s\"$
\n" ); document.write( "(1) $\"a+%2B+s+=+744\"$
\n" ); document.write( "(2) $\"8.5a+%2B+5.5s+=+4527\"$
\n" ); document.write( "Multiply (1) by $\"5.5\"$ and subtract from (2)
\n" ); document.write( " $\"8.5a+%2B+5.5s+=+4527\"$
\n" ); document.write( " $\"5.5a+%2B+5.5s+=+4092\"$
\n" ); document.write( " $\"3a+=+435\"$
