Equations

Definition

A literal equation is an equation that involves two or more variables.

Description

Literal equations involve multiple variables and are used to express relationships between them. For example, the formula for the area of a rectangle, 

A = lā€¢w

is a literal equation involving the variables l and w. Solving literal equations often involves isolating one variable in terms of the others.

Definition

A multi-step equation requires more than one step to solve.

Description

Multi-step equations involve multiple operations to isolate the variable. For example, solving 

3x + 2 = 11

requires subtracting 2 and then dividing by 3 to find x=3. These equations are common in algebra and require a systematic approach to solve.

In real-world applications, multi-step equations are used in complex problem-solving scenarios such as engineering and finance. Understanding how to solve multi-step equations helps students develop critical thinking and problem-solving skills.
