document.write( "Divide the second equation by 6 (both sides),\r\n" );
document.write( "\r\n" );
document.write( "and you will see that this equation become \r\n" );
document.write( "\r\n" );
document.write( "x + y = 7,\r\n" );
document.write( "\r\n" );
document.write( "exactly as the first equation is.\r\n" );
document.write( "\r\n" );
document.write( "So, you have here the system of two equivalent (depending) equations.\r\n" );

document.write( "\r\n" );
document.write( "The system has infinitely many solutions.\r\n" );
