Interactive Mathematics: Solving Systems Algebraically

In this simultaneous equations activity, pupils solve systems of equations. They graph systems of equations and write equations to fit given situations. This two-page activity contains three multi-step problems.

This lesson is all about systems of equations and their graphs. Algebra learners create and solve systems of equation using tables and graphing. They identify the point of intersection of a system of equation, and discover what the...

Do you need to graph lines to see the point? A thorough lesson plan provides comprehensive instruction focused on solving systems of equations by graphing. Resources include guided practice worksheet, skill practice worksheet,...

Solve systems of equations using the substitution or elimination method. Kids can practice by solving each of the five problems on this one-page worksheet.

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...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Elimination is another method for solving systems of equations, in addition to graphing and substitution. Sal's lecture is straightforward to understand, even for students who struggle with learning. By having a variety of options when...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

Learners explore the concept of solving systems of equations with two equations and two unknowns. In this solving systems of equations lesson, they work through problems of solving systems by substitution, elimination, and graphing....

Choose from multiple video tutorials to learn how to solve systems of equations that focus on pairs of linear equations in two variables. Topics include how to solve systems of equations by graphing, substitution method, elimination by...
