The answer explains how to say 'last night' and the past tense of 'salir' in Spanish.
La noche pasada salí con unos amigos.
Explanation: In Spanish, 'last night' is translated as 'la noche pasada.' The Pretérito Indefinido (simple past tense) of 'salir' for 'yo' is 'salí,' which means 'I went out.' Therefore, the complete sentence is 'La noche pasada salí con unos amigos,' meaning 'Last night, I went out with some friends.'
