6x+21 (Maybe)
Are you doing the buddy method, how is your teacher wanting to do this, When you respond I might have the correct answer
(buddy method) Multiply the 2x and 7 by the 3 giving you 6x+21 and then that's it you cant do anything else but I don't know if that's how you're teacher wants it done.

15+20=35
35=35
