Hi, I'm having a bit of trouble with the following problems:

Let S = {−5, −4, −3, −2, −1, 0, 1, 2, 3, 4, 5}. List all of the elements in each of the following sets.

(a) A=[x∈S l x is even and x is a multiple of 3].

b) B=[x∈S l if x is odd, then x is a multiple of 5]

I am really confused, as I'm not sure how to solve this. For a) there is no even number in set S that is also a multiple of 3. I have attempted this question many times without any luck, and would greatly appreciate any help.

Thanks
