What is the term for rearranging a formula to make a different variable the subject?

The term for rearranging a formula to make a different variable the subject is known as "Changing the Subject." This process involves manipulating the equation in such a way that the desired variable is isolated on one side of the equation while the other variables and constants are on the opposite side.

This concept is fundamental in algebra and is applied frequently in engineering and science, where equations often need to be rearranged to solve for specific variables based on the context of a problem. For instance, if you start with an equation that defines a specific relationship and you want to solve for a different variable, you systematically apply inverse operations to achieve that rearrangement.

The other terms, while they may describe parts of the process or related concepts, do not specifically encapsulate the action of isolating a variable in an equation. "Transforming" may imply a broader change without the clear intent of focusing on one variable, "Rearranging" could describe the movement of terms without emphasizing the notion of changing the subject, and "Substituting" refers to replacing one variable with another rather than the act of isolating a variable within an equation.
