How to delete record from only associated table with
has_and_belongs_to_many relation ship

I have two model hotel and theme and both has has_and_belongs_to_many
relationship
and third table name is hotels_themes, So I want to delete record only
from third tables hotels_themes.
hotels_themes;
+----------+----------+
| hotel_id | theme_id |
+----------+----------+
| 8 | 4 |
| 9 | 5 |
| 11 | 2 |
| 11 | 4 |
| 11 | 6 |
| 12 | 2 |
| 12 | 5 |
+----------+----------+
I want to delete record which match hotel_id and theme_id. Like sql query
delete from hotels_themes where hotel_id=9 and theme_id=5
