(7) Given the following pieces information, describe the set of solutions x such that Ax
(a) b is not in C(A).
(b) b is in C(A), and there is a vector c which satisfies the property that the set of
solutions of Ax = c is a plane.
(c) A is a 6 x 7 matrix, b is in C(A), and N(A") is a four dimensional vector space.
(d) A is a 3 x 3 matrix, and b is the first column of A. Additionally, Ax
= b:
O is solved
by both x =
and x =
