Using 1 statement to delete from 2 tables

[B. Fongo]

I'm using an older version of Mysql, and I know it doesn't support
trigger. 
What I'm trying to do, is to delete records from 2 tables (Sessions &
Cart).
 
 These experimental statements didn't help:
 
DELETE FROM Sessions INNER JOIN Cart on Sessions.id where Sessions.id
="$id"; 
DELETE FROM Sessions where Sessions.id ="$id" INNER JOIN Cart on
Sessions.id ";
 
I'll appreciate any suggestion on how to go about it.
 
 
Best regard
