Lesson Summary:

This lesson teaches how to solve for a variable, in this case R, in a literal equation with direct variation. Using a financial example of simple interest, the instructor demonstrates how to undo the multiplication of variables to isolate R. By either dividing each variable or dividing them all at once, the equation can be rearranged to have R by itself. This fundamental skill is important in many areas of math and finance.

Lesson Description:

Solving a literal equation with direct variation

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.

Questions answered by this video:
  • How do I get r by itself in the equation I=Prt?
  • How do I solve for r in the equation I=Prt?
  • How do I solve for one variable in a literal equation in terms of the other variables in the equation?
