document.write( "You messed up right there. You divided the left side\r\n" );
document.write( "by 2 and didn't divide the right side by 2.  You cannot\r\n" );
document.write( "divide only one side by something without dividing the\r\n" );
document.write( "other side by it too.  What you should have done is not\r\n" );
document.write( "to have divided the left side by 2, but instead factor out 2\r\n" );
document.write( "leaving the 2 outside the parentheses, like this:\r\n" );
