Part 2 of Solving Linear Systems of Equations with 2 variables, which is an overview of how to solve systems.
- What are systems of equations?
- What are the Algebraic methods for solving a system of equations?
- How do you solve y = 2x, x + y = 9?
- How do you solve a system of equations by graphing?
- How do you graph y = 2x and x + y = 9 and find where they intersect?
- How can you check to make sure that your solution is correct in a system of equations?
- How do you solve a system of equations using substitution?
- What is the substitution method for solving systems of linear equations?
- When you find x in a system of equations, how do you find y?
- How do you solve a system of equations using elimination or addition?
- What is the addition or elimination method for solving systems of linear equations?
- What is the solution to the system y = 2x and x + y = 9?
This lesson solves the same system of equations three different ways, using graphing, substitution, and elimination. Each method is explained and all steps are shown in detail. This is a great way to learn the methods of solving systems of equations algebraically.
