How do I solve to proof for x ⊆ p∪x?
p = power set
∪ = union
My dilemma is having the power set and union right next to each other. I am unsure of how to apply definitions to connected symbols.
Update:I must use Zermelo-Frankel Set Theory

Every set is a subset or equal to itself
x ⊆ x
Now: p∪x will at least have all the elements of x
So, x ⊆ p∪x
