Let $\"+a+\"$ = Janie's age now
\n" ); document.write( "Let $\"+b+\"$ = Matt's age now
\n" ); document.write( "----------------------------
\n" ); document.write( "(1) $\"+a+=+b+-+3+\"$
\n" ); document.write( "(2) $\"+a+%2B+5+%2B+b+%2B+5+=+29+\"$
\n" ); document.write( "----------------------------
\n" ); document.write( "(1) $\"+a+-+b+=+-3+\"$
\n" ); document.write( "(2) $\"+a+%2B+b+=+19+\"$
\n" ); document.write( "----------------------
\n" ); document.write( "Add the equations
\n" ); document.write( " $\"+2a+=+16+\"$
\n" ); document.write( " $\"+a+=+8+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+a+%2B+b+=+19+\"$
\n" ); document.write( "(2) $\"+8+%2B+b+=+19+\"$
\n" ); document.write( "(2) $\"+b+=+11+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "Janie is 8
\n" ); document.write( "-------------
\n" ); document.write( "check:

\n" ); document.write( "(1) $\"+8+=+11+-+3+\"$
\n" ); document.write( "(1) $\"+8+=+8+\"$
\n" ); document.write( "OK
\n" ); document.write( "You can check (2)\r
