The solution to the first problem should be -29, not positive 29.
In this lesson, the instructor explains how to solve one-step equations by isolating the variable. They provide two examples of equations and demonstrate how to solve for the variable by reversing the operation being done to it. The first example involves subtracting a variable from a negative number, while the second example requires finding a common denominator to subtract fractions. By following these steps, solving one-step equations becomes a relatively straightforward process that can be applied to a wide range of problems.
How to solve one step equations
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
