Does \"N\" stand for nickels? If so,
\n" ); document.write( "\"Q+=+5\"
\n" ); document.write( "\"D+=+2Q\"
\n" ); document.write( "There are \"16\" coins in all, so
\n" ); document.write( "\"Q+%2B+D+%2B+N+=+16\"
\n" ); document.write( "Now I can do substitutions
\n" ); document.write( "\"Q+%2B+2Q+%2B+N+=+16\"
\n" ); document.write( "\"3Q+%2B+N+=+16\"
\n" ); document.write( "And,since \"Q+=+5\"
\n" ); document.write( "\"3%2A5+%2B+N+=+16\"
\n" ); document.write( "\"15+%2B+N+=+16\"
\n" ); document.write( "Subtract \"15\" from both sides
\n" ); document.write( "\"N+=+1\"
\n" ); document.write( "Therefore,
\n" ); document.write( "\"Q+=+5\"
\n" ); document.write( "\"D+=+10\"
\n" ); document.write( "\"N+=+1\"
\n" ); document.write( "
\n" );
