Section 2.4

Solving a System of Equations with Matrices

In section 2.2, you learned how to solve systems of equations in two variables using the Substitution Method or the Elimination Method. These methods worked well for problems involving two variables, but are cumbersome for problems involving more than two variables. Of course, problems involving more than two variables are what you are most likely to encounter in business and finance so we’ll need more efficient techniques involving matrices to solve these systems.
