The video tutorial on 'The Magic of Math' channel covers rewriting equations and formulas. It begins with an introduction to literal equations, explaining their use with multiple variables. The lesson progresses to demonstrate how to rewrite equations in different forms, such as slope-intercept and standard form, using inverse operations. The tutorial also covers rewriting formulas to solve for specific variables, using examples like the area of a triangle and the volume of a pyramid. Finally, it addresses solving complex equations with multiple variables, emphasizing factoring techniques.

What is a literal equation?

• An equation with only one variable

• An equation with no variables

• An equation written using two or more variables

• An equation that cannot be solved
