this should do, presuming you want to delete from Statements table. otherwise, you just reverse the 2 table names
DELETE STATEMENTS A
WHERE EXISTS( SELECT NULL 
   FROM reverselines T
       WHERE A.ACCNO = T.ACCNO AND A.FIYID= T.FIYID AND A.PERID = T.PERID AND A.LINENO = T.LINENO
  )

You can't use table or view name before the 'From' clause in plsql.  so right statement should be like this:

 
DELETE 
FROM STATEMENTS A, REVERSELINES T
WHERE A.ACCNO = T.ACCNO AND A.FIYID= T.FIYID AND A.PERID = T.PERID AND A.LINENO = T.LINENO
