Systems of Equations Word Problems Worksheet: Using Substitution
About This Product
This engaging math activity allows high school students in grades 8-11 to gain a realistic understanding of solving systems of equations (with two variables and even three variables) using the substitution method.
Using real-life examples including shopping, basketball scores, and even YouTube videos, your students learn a simple algebraic method of solving a system of equations: the substitution method.
They also gain practice writing simple equations with variables to represent real-life word problem scenarios.
There is even a more challenging system of equations with three variables included for your students who can handle an extra challenge: this one is so satisfying once they figure out how to solve it!
A step-by-step sample problem that you can use as a teaching aid and a complete answer key are also included so that this lesson requires no prep!
