document.write( "\r\n" );
document.write( "From the condition, you have this system of 2 equations in 2 unknowns\r\n" );
document.write( "\r\n" );
document.write( "    x +  y =  290       (1)   (total number of tickets)\r\n" );
document.write( "\r\n" );
document.write( "   8x + 4y = 1440       (2)   (total money)\r\n" );
document.write( "\r\n" );
document.write( "where x = # of adult tickets,  y = # of student tickets.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From equation (1), express y = 290-x  and substitute it into equation (2), replacing y.  You will get then\r\n" );
document.write( "\r\n" );
document.write( "    8x + 4*(290-x) = 1440.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the last equation\r\n" );
document.write( "\r\n" );
document.write( "    x = \"%281440-4%2A290%29%2F%288-4%29\" = 70.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  70 adult tickets and 290-70 = 220 student tickets.\r\n" );
document.write( "\r\n" );

document.write( "CHECK.   8*70 + 4*220 = 1440 dollars.   ! Correct !\r\n" );
