Solving Literal Equations

In this section, we learn how to solve a formula for a specified variable. This is also known as solving literal equations. This is extremely useful when working with generic formulas. Let us take the example of the distance formula. This tells us that distance traveled (d) is equal to the rate of speed (r) multiplied by the amount of time traveled (t). d = r x t: we can solve the formula for time or rate if we would like. This would enable us to find the time traveled given the rate of speed and the distance. It would also enable us to find the rate of speed, given the time traveled and the distance.
