Solving Systems of Linear Equations Using Substitution and Elimination with 2 Equations 2 Variables

Learn how to solve systems of linear equations using two powerful methods: substitution and elimination! This comprehensive video will guide you through 10 detailed examples, helping you master both techniques to find the point of intersection for two lines. We'll start with the Substitution Method, demonstrating how to isolate one variable in an equation and substitute its expression into the other equation. You'll see how this reduces the system to a single equation with one variable, making it easy to solve. Next, we'll dive into the Elimination Method, where you'll learn to strategically add or subtract equations to cancel out one of the variables. We'll cover examples where you can directly add/subtract, as well as more challenging cases where you need to multiply one or both equations by a constant before eliminating a variable. By the end of this tutorial, you'll have a strong understanding of both methods and be able to confidently solve various systems of equations! * Organized List of My Video Lessons to Help You Raise Your Scores & Pass Your Class.
