You can use INTERVAL as follows;
SQL> with t as
  2  (
  3    select     to_date('08-FEB-91','dd-MON-rr') as dt from dual union
  4    select     to_date('27-AUG-03','dd-MON-rr') as dt from dual union
  5    select     to_date('30-JUL-07','dd-MON-rr') as dt from dual
  6  )
  7  select t.dt
  8  from t
  9  where t.dt > sysdate - interval '7' year
10  /
DT
30-JUL-2007 00:00:00
