Example 2: Variables on Both Sides, Linear Equations, Algebra I

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. 

Concepts are only valuable if they are applicable. An informative resource uses concepts developed in lessons 26 and 27 in a 36-part series. Scholars write equations and solve for missing side lengths for given right triangles....

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...

Sal demonstrates how to solve an equation. He begins by saying that the variable needs to be isolated. Then, he shows how to move numbers on either side of the equal sign to isolate the variable. Finally, he verifies answers by plugging...

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since variables are on both sides of the equation, it is important to verify the answer by...

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

Solving single variable inequalities is explored in this video. The example that Sal shows here contains fractions, shows the need to reverse the inequality because he multiples by a negative number during his computation, and shows the...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or...

School subjects connect when your young scholars use math to edit English. Math allows you to convert an entire paragraph into a simple equation or inequality. Examples encourage learners to write expressions, equations, and inequalities...

Use an understanding of equality to find solutions of quadratics graphically. A well-designed lesson illustrates the relationship between the right and left sides of an equation graphically. With one side quadratic and the other side...
