Matrix equation The Two linear systems using the same set of variables are equivalent if each of the equations in the second system can be derived algebraically from the equations in the first system, and vice versa. Two systems are equivalent if either both are inconsistent or each equation of each of them is a linear combination of the equations of the other one. It follows that two

SOLVING LINEAR SYSTEMS Linear systems Ax = b occur widely in applied math-ematics. They occur as direct formulations of “real world” problems; but more often, they occur as a part of the numerical analysis of some other problem. As examples of the latter, we have the numerical solution of systems of nonlinear equations, ordinary and par-tial diﬀerential equations, integral equations, and
