The sum of the reciprocal of a number and the reciprocal of 3 less than the number is 6 times the reciprocal of the original number.

\n" ); document.write( ":
\n" ); document.write( "let n = original number
\n" ); document.write( ":
\n" ); document.write( "\"1%2Fn\" + \"1%2F%28%28n-3%29%29\" = \"6%2Fn\"
\n" ); document.write( "multiply by n(n-3), resulting in
