document.write( "Your starting equation is\r\n" );
document.write( "\r\n" );
document.write( "     = 25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the same as\r\n" );
document.write( "\r\n" );
document.write( "     = 25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Multiply both sides by 4.  You will get an equivalent equation\r\n" );
