We turn these into a single vector equation: x = (x1 x2 x3) = x2(1 1 0) + x3(− 2 0 1). This is the parametric vector form of the solution set. Since x2 and x3 are allowed to be anything, this says that the solution set is the set of all linear combinations of (1 1 0) and (− 2 0 1) . In other words, the solution set is.Combining the above results, the elements of the foregoing notions are endowed with compact representations formulated here by Leibnizian and nested sum representations.
