document.write( "You start from this equation\r\n" );
document.write( "\r\n" );
document.write( "     = 5\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This equation is equivalent to\r\n" );
document.write( "\r\n" );
document.write( "    3x + 4 =  = 32.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore,\r\n" );
document.write( "\r\n" );
document.write( "    3x = 32 - 4\r\n" );
document.write( "\r\n" );
document.write( "    3x = 28\r\n" );
