Let X be the set of nonempty sets of (-1, 0, 1) and define a relation R on X as follows: For all sets s and tin X, SR t the sum of the elements in s equals the sum of the elements in t. It is a fact that R is an equivalence relation on X. Use set-roster notation to list the distinct equivalence classes of R. (Enter your answer as a comma-separated list of sets. Enter EMPTY or for the empty set.)
