Let \"+b+\" = Bill's age now
\n" ); document.write( "\"+16+\" = Chris's age now
\n" ); document.write( "-----------------------
\n" ); document.write( "\" when Bill was the age Chris is now. \"
\n" ); document.write( "This is when Bill was \"+16+\"
\n" ); document.write( "--------------------------------
\n" ); document.write( "The difference in their ages never changes
\n" ); document.write( "It is \"+b+-+16+\"
\n" ); document.write( "\" the age Chris was \"
\n" ); document.write( "Chris was \"+16+-+%28+b+-+16+%29+=+32+-+b+\"
\n" ); document.write( "----------------------------------
\n" ); document.write( "\" Bill is three times \"
\n" ); document.write( "So, Bill's present age is:
\n" ); document.write( "\"+b+=+3%2A%28+32+-+b+%29+\"
\n" ); document.write( "\"+b+=+96+-+3b+\"
\n" ); document.write( "\"+4b+=96+\"
\n" ); document.write( "Bill is 24
\n" ); document.write( "---------------
\n" ); document.write( "check the answer:
\n" ); document.write( "The difference in their ages is \"+24+-+16+=+8+\"
\n" ); document.write( "---------------------------------------
\n" ); document.write( "\" when Bill was the age Chris is now. \"
\n" ); document.write( "When Bill was \"+16+\"
\n" ); document.write( "---------------------
\n" ); document.write( "\" the age Chris was \"
\n" ); document.write( "Chris was \"+16+-+8+=+8+\"
\n" ); document.write( "----------------------
\n" ); document.write( "\" Bill is three times \"
\n" ); document.write( "Bill is \"+3%2A8+=+24+\"
\n" ); document.write( "OK
\n" ); document.write( "Hope I got it!
\n" ); document.write( "
