Solving Systems of Equations

In this simultaneous equations worksheet, students solve and complete 7 various types of problems. First, they solve graphically the system of equations shown. Then, students find the number of solutions that each pairs of equations...

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...

In this solving equations worksheet, 9th graders solve and complete 21 various types of problems. First, they use the method shown to find the value of xin each equation. Then, students use an algebraic approach to solve the magic...

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. 

Now there are parentheses in these equations? As the lessons continue in this series, equations get progressively more complex. Eighth graders solve equations by applying the distributive property before using inverse operations. 

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Show how matrices can be helpful for solving systems of equations. The video illustrates an example of solving a two-variable system utilizing Cramer's Rule. The instructor shows how to find the determinant of each matrix and then uses...

Which method of solving systems is the best? Individuals watch the same system solved using elimination, then substitution, and finally graphing. They can compare the different methods and see how each method results in the same solution.

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

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...
