In this lesson, you will learn how to solve a system of linear equations by using the triangle method. The triangle method allows you to simplify any system of equations into triangle form using row operations on the equations. We can multiply an equation by a number, swap equations, and add equations.

We will show how to use these row operations to transform any linear system into triangle form, whereby we can then use substitution to arrive at the final solution.
