on a ring with two substituents, an activating and a deactivating group on a benzene molecule...is there a general rule that says that the activating group is more influential in directing the substituent to the correct place over the deactivating?

I recall a problem where i believe there was a deactivating group and para to that was an activating group..and the substituent was placed meta to the deactivating group (or ortho to the activating group)

the most activating group will always direct, so between a deactivating group and an activating group, the activating group will direct
