Answer: Nous sommes très contents de vous voir.
Step-by-step explanation:
Nous très somme’ contents de vous voir => we are very happy to see you.
Nous très contents de vous voir => we very happy to see you.
Without the verb ‘sommes,’ which mean ‘are’, the sentence does not have proper grammar. Once you add the ‘sommes’ you can better understand what they are trying to say.
Hope this helped! :)
