This video tutorial introduces literal equations, which are equations with multiple variables. It explains how to solve these equations by isolating a specific variable, resulting in an expression rather than a numerical value. The tutorial provides several examples, demonstrating the process of isolating variables like B and C in different equations. The video emphasizes the consistent technique used across various examples, highlighting the importance of understanding the underlying principles of solving literal equations.

What is a literal equation?

• An equation with no variables

• An equation with only one variable

• An equation with more than one variable

• An equation with only numbers

How do you solve the equation 4ABC = 32 for C?

• C = 32 * 4AB

• C = 32 / (4AB)

• C = 32 + 4AB

• C = 32 - 4AB
