Let $\"+b+\"$ = Bob's age now
\n" ); document.write( "Let $\"+c+\"$ = Carol's age now
\n" ); document.write( "------------------------------
\n" ); document.write( "(1) $\"+b+%2B+c+=+100+\"$
\n" ); document.write( "(2) $\"+b+-+16+=+3%2A%28+c+-+16+%29+\"$
\n" ); document.write( "------------------------------
\n" ); document.write( "Add (1) and (2)
\n" ); document.write( "(2) $\"+b+-+16+=+3c+-+48+\"$
\n" ); document.write( "(2) $\"+-b+%2B+3c+=+32+\"$
\n" ); document.write( "(1) $\"+b+%2B+c+=+100+\"$
\n" ); document.write( "------------------------
\n" ); document.write( " $\"+4c+=+132+\"$

\n" ); document.write( "(1) $\"+b+=+100+-+33+\"$
\n" ); document.write( "(1) $\"+b+=+67+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "The difference in their ages never changes
\n" ); document.write( "The difference is: $\"+67+-+33+=+34+\"$ yrs
