document.write( "I don't understand this problem at all and I am having trouble even being able to find it in my text book. If you could help me solve for x on this one, I think it would help me be able to better understand how to do it. Then, I will also have an example to look back on when working on other similar problems. Thank you for your time and help! \n" );
