Removal of record from the second table on selection from the first table?

Question

MySQL

Hello.
Suppose there are two tables in the database: t1 and t2. In t1, each entry has a unique id. There are several records in t2 containing a unique id from t1. I need to remove from t2 all records that contain a unique id from t1.
Roughly speaking, I need to save the result of the selection from t1 to some variable, and then delete all records from t2 by the value of this variable. All this needs to be done somehow only in SQL.
Thanks everyone for the replies, I solved this issue using the ANY operator.

DELETE FROM t2 WHERE id = ANY(SELECT id FROM t1 WHERE id = 1 )

Answer 1

delete from t2 where id in (select id from t1 where .......)

Answer 2

DELETE t2.* FROM t1
  JOIN t2 ON t1.id = t2.`уникальный id из t1`
WHERE <условие на t1>;
