Literal Equation
A literal equation is an equation that involves two or more variables
A literal equation is an equation that involves two or more variables. Unlike a regular equation where you solve for a single variable, a literal equation allows you to solve for a specific variable in terms of the others. These equations are often used in various fields of science and engineering to relate different physical quantities.
To better understand literal equations, let’s look at an example. Consider the equation for the circumference of a circle:
C = 2πr
In this equation, C represents the circumference and r represents the radius of the circle. This is a literal equation because it involves two variables, C and r. By rearranging the equation, you can solve for either variable in terms of the other.
For instance, if you want to solve for the radius, you can divide both sides of the equation by 2π:
r = C / (2π)
Similarly, if you want to solve for the circumference, you can multiply both sides of the equation by 2π:
C = 2πr
Literal equations are helpful because they allow us to manipulate equations to solve for a specific variable depending on the problem at hand. They are particularly useful in situations where you have multiple variables that are interrelated and you need to find the value of one variable in terms of the others.
