\r\n" );
document.write( "1.  Add \"y\" to both sides. You will get an equivalent equation\r\n" );
document.write( "\r\n" );
document.write( "    2x = 1 + y.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2.  Subtract \"1\" from both sides you will get an equivalent equation\r\n" );
document.write( "\r\n" );
document.write( "    2x - 1 = y.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "3.  It is equivalent to \r\n" );
document.write( "\r\n" );
document.write( "    y = 2x - 1.\r\n" );
