Let Finn's age now = $\"+f+\"$
\n" ); document.write( "Let Ellen's age now = $\"+e+\"$
\n" ); document.write( " $\"+f+%2B+10+\"$ = Finn's age 10 years from now
\n" ); document.write( " $\"+e+-+6+\"$ = Ellen's age 6 years ago
\n" ); document.write( "-------------
\n" ); document.write( "(1) $\"+f+%2B+e+=+40+\"$
\n" ); document.write( "(2) $\"+f+%2B+10+=+4%2A%28+e+-+6+%29+-+1+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "(2) $\"+f+%2B+10+=+4e+-+24+-+1+\"$
\n" ); document.write( "(2) $\"+4e+-+f+=+35+\"$
\n" ); document.write( "(1) $\"+e+%2B+f+=+40+\"$
\n" ); document.write( "Add the equations
\n" ); document.write( " $\"+5e++=+75+\"$
\n" ); document.write( " $\"+e+=+15+\"$
\n" ); document.write( "and, since
\n" ); document.write( "(1) $\"+e+%2B+f+=+40+\"$
\n" ); document.write( "(1) $\"+15+%2B+f+=+40+\"$
\n" ); document.write( "(1) $\"+f+=+25+\"$
\n" ); document.write( "Finn's age now is 25
\n" ); document.write( "Ellen's age now is 15 \n" ); document.write( "

\n" );
