Web1st step. Solution: The relation R on the set of integers ( Z) is defined as follows: x R y if and only if 3 x − 5 y is even. To describe the equivalence classes of R, we need to find sets of integers that are related to each other under this relation. In other words, we need to identify sets of integers that produce even values when plugged ... WebThis equivalence relation partitions our class into subsets where everyone in a given subset is related to everyone else in that subset, no person is in two different subsets, and the union of all the subsets is the entire class.
