Solution Preserving Operations
Learn to represent a linear system as an augmented matrix and to use the elementary (solution preserving) row operations.
We'll cover the following...
Earlier, while defining linear systems, we discussed the different possibilities of the solution of a linear system. In this chapter, we’ll describe how we can achieve those possibilities. Let’s start by learning the foundations before moving on to a systematic approach.
Augmented matrix
We’ve already learned two different representations of a system of linear equations. We started with a set of linear equations, that is,
...
