TEST BANK FOR Introduction to Linear Algebra with Applications By James DeFranza, Daniel Gagliardi Converted

In Section 1.1 of the text, Gaussian Elimination is used to solve a linear system. This procedure utilizes three operations that when applied to a linear system result in a new system that is equivalent to the original. Equivalent means that the linear systems have the same solutions. The three operations are: • Interchange two equations. • Multiply any equation by a nonzero constant. • Add a multiple of one equation to another. When used judiciously these three operations allow us t...
