You can put this solution on YOUR website!
You were correct, but you have 2 unknowns and
\n" ); document.write( "only 1 equation. The other equation is:
\n" ); document.write( "\"+x+%2B+y+=+325+\"
\n" ); document.write( "Multiply both sides of this equation by \"+25+\"
\n" ); document.write( "and subtract from the other equation
\n" ); document.write( "\"+25x+%2B+40y+=+10000+\"
\n" ); document.write( "\"+-25x+-+25y+=+-8125+\"
\n" ); document.write( "\"+15y+=+1875+\"
\n" ); document.write( "\"+y+=+125+\"
\n" ); document.write( "and, since
\n" ); document.write( "\"+x+%2B+y+=+325+\"
\n" ); document.write( "\"+x+%2B+125+=+325+\"
\n" ); document.write( "\"+x+=+200+\"
\n" ); document.write( "200 balcony tickets were sold
\n" ); document.write( "125 1st floor tickets were sold
\n" ); document.write( "
\n" ); document.write( "
\n" );
