\n" ); document.write( "The sum of Carol's and Sandy's ages (C+S) is 47. In 10 years Carol (C+10)
\n" ); document.write( "will be 10 years older than(10 more than) Sandy was 7 years ago (S-7).
\n" ); document.write( "`
\n" ); document.write( "(C+S) = 47
\n" ); document.write( "(C+10) = 10 more than (S-7), which means \"(S-7) plus 10\"
