Solve Linear Equations with Substitution ✏️

In this video I will show you how to solve a system of linear equations using substitution! If you are wondering just how does substitution work in math, this video will walk you through the substitution method for solving a linear system using an example.

Solving a linear system using substitution is a much faster and more accurate way of solving a linear system compared to graphing two lines to find the point of intersection. The key here is looking for an expression that already has a variable isolated. This makes it possible to substitute one expression into another to simplify and solve.

This example will show you how to find the point of intersection of two lines without graphing them!
