Answer:
A ellos les gusta las enchiladas.
A ellos les gusta comer enchiladas
Explanation:
First we must divide each part of the sentence
preposition = A
pronoun = ellos
verb = gusta
verb = comer
article = las
noun = enchiladas
In this example in Spanish we need the preposition "A" at the beginning of the sentences to indicate who like enchiladas
In English, we don't need this preposition because we can say:
They like to eat enchiladas
They like enchiladas
If we translate the sentence literally would be Ellos gusta comer enchiladas, this form is incorrect because we don't know "who".
For example:
We are in a restaurant and there are 5 groups of people eating, but only one group like to eat enchiladas.
If we only say Ellos gusta comer enchiladas, we won't know the correct group.
If we say A ellos, in this case we are pointing a specific group in the restaurant.
Venga a nuestra casa is used for someone who should respect or who is elderly so this would be the right choice.
Ven a nuestra casa would be used to refer to maybe your close friends or people you can be casual with :)
