document.write( "Let x be the number of adult tickets.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the number of student tickets is  (820-x).\r\n" );

document.write( "The revenue equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    12x + 8*(820-x) = 9128.\r\n" );

document.write( "\r\n" );
document.write( "From the equation, express x  and calculate\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x =  = 642.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  642 adult tickets and  820-642 = 178 student tickets.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   12*642 + 8*178 = 9128.    ! Precisely correct !\r\n" );
