in the first example, your feasible set is just one point (the one
that fulfills the 3 equations) and thus there is only this one point
which can maximize the objective function. In the second case, the
feasible set is a line. But the simplex algorithm tries to find an
optimizing value of the objective on a convex polyhedron. So the
simplex function may be inappropriate to find all feasible solutions.
