You can put this solution on YOUR website!
I thought 13370 was mistyped. But, if not:
\n" ); document.write( "Which one is Gandalf?
\n" ); document.write( "Where it says \" I am \", I will call the present age $\"+a+\"$
\n" ); document.write( "Where it says \" you \" , I will call the present age $\"+b+\"$
\n" ); document.write( "--------------------------------------------------
\n" ); document.write( "\" I'm three times as old as you were when I was as old as you are now.\"
\n" ); document.write( "---------------------
\n" ); document.write( "\" as you are now \"
\n" ); document.write( "That would be $\"+b+\"$
\n" ); document.write( "\" when I was as old as you are now.\"
\n" ); document.write( "I'll make the assumption that \"I\" am older than \"you\"
\n" ); document.write( "The difference in their ages is always $\"+a+-+b+\"$
\n" ); document.write( "So I was $\"+a+-+%28+a+-+b+%29+\"$
\n" ); document.write( "----------------------------
\n" ); document.write( "\" as you were \"
\n" ); document.write( "That would be:
