Solving Equations with Addition and Subtraction

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...

Discover the joy and excitement of improving your math fluency through four different puzzles. Combine those with 25 different ways to represent numbers and you have hours of enjoyment that can be fun outside of the classroom as well.

Oh no, there are decimals! A resource shows a method to solve a two-step equation that contains decimals. Using a process of clearing the decimals, the presenter converts the equation into a basic two-step equation with whole numbers. At...

There is more than one way to solve an equation. Scholars watch as the presenter solves a one-step equation with fraction multiplication two different ways. Viewers see how to use a reciprocal to solve the equation and also how to clear...

Apply decimal operations to solving equations. Learners first observe two examples of one-step linear equations being solved. They then watch as each equation is solved by either adding or subtracting decimals using strategies they...

This inequality word problem would make a good warm-up activity for a class studying single-variable inequalities. This video creates and solves an inequality based on a short-word problem about unit cost.

Not only can equations have many steps to solve, but those steps can look very different from equation to equation. The narrator of the video lesson explains the steps to solving six different multi-step equations. He provides...

With two examples, the presenter shows how to solve a two-step linear equation that contains decimals. Prior to solving the first example, the presentation reviews the steps to solving any two-step linear equation. The examples require...
