Solving Linear Systems by Substitution

With a whopping total of 66 questions, here is a resource that provides a full variety of systems of equations questions using elimination and substitution solution methods.

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.

Another method for solving systems of equations, in addition to graphing, is the focus of this video, as Sal demonstrates the substitution method. It's important to understand that there is more than one way to solve any problem,...

Utilize linear systems to solve age-related word problems. The video tutorial shows how to write and solve a linear system from a set of given information. After solving the system, the instructor explains how to examine the solution for...

Now that budding mathematicians have figured out linear systems, its time to try nonlinear! A video tutorial outlines the steps of solving a linear-quadratic system of equations. The instructor demonstrates each step of the process using...

Substitution is a key concept in algebra—with many more uses than just solving linear systems. Build an integral foundational skill using a video tutorial and practice options in a well-designed lesson. The video offers multiple examples...

Let the learners take the driving wheel! The class solves systems of linear equations and applies the concepts of systems to solve a real-world situation about parking cars and buses. They then use calculators to create a visual of their...
