Literal equation
Calculate literal equation in Grade 9 math — Explanation Think of a literal equation as a regular math puzzle, but with more characters! Part of Functions and Graphing for Grade 9.
Key Concepts
Property A literal equation is an equation with more than one variable. A formula is a type of literal equation.
Examples The distance formula $d = rt$ is a literal equation with three variables. The equation for a line, $y = mx + b$, is a literal equation with four variables. The formula for the area of a rectangle, $A = lw$, is a literal equation solved for the area.
Explanation Think of a literal equation as a regular math puzzle, but with more characters! Instead of just solving for 'x', you might be solving for 'y', 'r', or even 'C'. Your goal is still the same: get that one specific letter all by itself on one side of the equals sign. The answer won't be a single number, but a new recipe using the other variables.
