. In the following either prove that the set W is a subspace of the vector space V or give a counterex- ample to show that it is not. (a) V = R4, W is the set of all (x1, x2, x3, x4) such that r1 = rž. (b) V = R³, W is the set of all (x1, x2, x3) such that 2x1 =-x2 + x3. (c) V = R³, W is the set of all (x1, 2, x3) such that r1 + x2 + x3 = -1.
