Let $\"+k+\"$ = Karen's age
\n" ); document.write( "Let $\"+j+\"$ = Joe's age
\n" ); document.write( "-----------------------
\n" ); document.write( "(1) $\"+k+=+4j++%2B+13+\"$
\n" ); document.write( "(2) $\"+k+%2B+j+=+73+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "Substitute (1) into (2)
\n" ); document.write( "(2) $\"+4j+%2B+13+%2B+j+=+73+\"$
\n" ); document.write( "(2) $\"+5j+%2B+13+=+73+\"$
\n" ); document.write( "(2) $\"+5j+=+60+\"$
\n" ); document.write( "(2) $\"+j+=+12+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+k+%2B+j+=+73+\"$
\n" ); document.write( "(2) $\"+k+=+73+-+j+\"$
\n" ); document.write( "(2) $\"+k+=+61+\"$
\n" ); document.write( "Karen is 61
