how do i make "invitarlos a la fiesta" a command?

Question

Nina is organizing a party at the last minute and giving everyone instructions. Use the words in parentheses to create more commands.

Berenice, llama a tus amigos. (invitatlos a la fiesta)

Answer 1

"Ud." command form = present yo form with the "o" changed into either an "e" (for -ar verbs) or an "a" (for -er and -ir verbs)

Entonces: invitelos a la fiesta.

However if you're talking to a close friend you'll want to use "tu" form in which case all you do is add an "s".

Entonces: inviteslos a la viesta.
