document.write( "From the second equation, substitute y = 3x into the first equation, replacing \"y\" there. You will get\r\n" );

document.write( "    3x = -x - 8.\r\n" );

document.write( "It is just single equation for one variable x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    3x + x = -8\r\n" );
document.write( "\r\n" );

document.write( "     x = -8/4 = -2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then from the second given equation,  y = 3x = 3*(-2) = -6.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.   x= -2;  y= -6.\r\n" );
