THEOREM 1.18 Structure of the Solution Set of Ax = b
Let Ax = b be a linear system. If p is any particular solution of Ax = b
and h is a solution of the corresponding homogeneous system Ax = 0,
then p + h is a solution of Ax = b. Moreover, every solution of Ax = b
has this form p + h, so that the general solution is x = p + h where
Ah = 0.
