1. What is a System of Equations?
Mathematical word problems may be represented in equation form using a system of equations. Learn about modeling word problems into systems of equations, how to graph these equations on a coordinate system, and how to solve for the solutions of the system using the plotted graph of the equations.
2. How to Solve Systems of Linear Equations by Graphing
Systems of linear equations are important in many branches of math and science, so knowing how to solve them is important. In this lesson, learn one way to find the solution of a system of linear equations by graphing.
3. Solving a System of Equations with Two Unknowns
When you have two variables and two equations, is solving the problem four times as hard? No! Not when you use the substitution or elimination method to solve systems of equations. We'll practice both in this lesson.
4. Solving Problems Involving Systems of Equations
Did you ever encounter a problem where you seem to have lots of information, but still have a couple of critical numbers missing? In this lesson, we'll practice solving word problems that require us to set up systems of equations.
