let x=# orchestra seats, so 650 - x =# balcony seats.
\n" ); document.write( "Then 20x + 12(650 - x) = 11600.
\n" ); document.write( "20x - 12x = 11600 - 7800,
\n" ); document.write( "8x = 3800,
\n" ); document.write( "x = 475 orchestra tickets, and 175 balcony tickets.
\n" ); document.write( "
\n" ); document.write( "
