Simplifying Equations of the Form ax+b=cx+d

This two page worksheet contains 32 problems to solve. There are examples given for each set of problems. The first set is to work on adding or subtracting a term to get the variable by itself. The second set is about dividing both sides...

Challenge your mathematicians to simplify and solve a variety of different equations. This instructional activity focuses on multi-step problems that begin with combining like terms and advance toward solving equations with variables on...

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...

Where did all these variables come from, anyway? The previous lessons in the series ask learners to solve multi-step equations using the distributive property, combining like terms, and using inverse operations. Now scholars solve...

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. 

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. 

A brief presentation with laser-like focus, this video talks young mathematicians through the mechanics of simplifying algebraic fractions by factoring trinomials. While the factoring itself is assumed to be a mastered skill, the...

So you have the same variable more than once on the same side? No problem. Just simplify before trying to solve. That means, combine the like terms. Watch as the teacher shows you how to do that.

Math enthusiasts and riddle gurus are sure to love a mind-bending puzzle involving a king, a scale, and a counterfeit coin. Middle and high schoolers work through a video that describes a mathematician's challenge to find a false coin in...
