Step-by-step explanation:

Chapter 2, Exercise 1: Prove that the empty set is a subset of every set.

My first intention would have been:

Let X be an arbitrary set, then ∅∪X=X∪∅=X⟹∅⊆X∅∪X=X∪∅=X⟹∅⊆X since S⊆S∪TS⊆S∪T and T⊆S∪TT⊆S∪T for arbitrary sets SS and TT. XX was arbitrary, thus the assertion holds. □◻

But I'm not completely sure, if the prove is complete, as I haven't seen this version anywhere within a quick google search. What would you say

if u like this u can mark me brainliest.
