Key Concepts

Linear Equation

A linear equation is an equation that involves variables raised only to the first power and represents a straight line when graphed. It typically takes the form ax + b = c, where a, b, and c are constants, and is solved through basic arithmetic operations.

Isolating the Variable

Isolating the variable involves manipulating the equation to get the variable term on one side of the equation. This is achieved by applying arithmetic operations like addition or subtraction to both sides, ultimately solving for the unknown.

Inverse Operations

Inverse operations are pairs of mathematical operations that cancel each other out, such as addition with subtraction or multiplication with division. They are essential in solving equations as they allow one to systematically undo operations applied to the variable.
