document.write( "    -4y = -8;   hence,  y =  = 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Substitute the found value y= 2 into the second equation.  You will get then\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    -x + 2 = 4;   hence,  -x = 4-2 = 2,   or  x = -2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  x= -2;  y= 2.\r\n" );
