Literal Equations & Formulas

A literal equation is an equation that contains two or more variables. It is often solved for one variable in terms of the others.

$$b = y - mx$$

$$a = \frac{ub}{k}$$

$$r = \frac{d}{t}$$

$$a = \frac{p}{w}$$

Isolating a variable means rearranging the equation so that the variable is on one side by itself.

Identify the variable you want to isolate and determine how it is related to the other variables.

$$x = \frac{15}{3} = 5$$

Rearranging formulas allows you to solve for a specific variable, making it easier to use the formula in different contexts.

$$y = 10 + 2x$$
