In this lesson, we learn how to solve literal equations for both x and y. The key is to isolate the variable you're trying to solve for and undo any operations that are preventing it from being alone. In solving for x, we add y to both sides and then divide by 7. In solving for y, we rewrite the equation to see that 7x is being added to y, and then we subtract 7x and divide by -1. By following these steps and understanding the operations involved, we can successfully solve for both x and y in any literal equation.

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.
