Lesson Summary:

In this lesson, we learn how to solve literal equations where we isolate one variable in a formula that has other variables as well. The lesson covers examples involving formulas such as distance equals rate times time, interest equals principal times rate times time, perimeter formulas, and equations with multiple instances of the variable to be solved. By following a systematic process of isolating the variable and dividing by the coefficient, we can solve these equations and find the value of the unknown variable.

Lesson Description:

Part 1 of solving for one variable in a formula.

    This lesson, although it may seem a bit basic, is quite challenging to many beginning Algebra students. You will learn in this lesson how to get one variable all by itself when given a formula. A couple of example formulas are shown and variables are solved for.
