Solution2.5 Solving systems of equations, preliminary approach We turn instead to a recipe for solving systems of linear equations, a step-by-step procedure that can always be used. It is a bit harder to see what the possibilities are (about what can possibly happen) and a straightforward procedure is a valuable thing to have. We will see later in this chapter that when a system of linear equations is written using matrices, the basic unknown in the reformulated system is a column vector. A similar formulation will also be given in Chapter 7 for systems of differential equations.
