Key Concepts

Linear Equations

A linear equation is an equation in which the variable appears only to the first degree and its graph yields a straight line. These equations are foundational in algebra and are solved by performing arithmetic operations that simplify the equation to a form where the variable is isolated.

Properties of Equality

The properties of equality allow you to perform the same operation on both sides of an equation without changing the equation's balance. This fundamental property is crucial when solving equations as it ensures the equality remains valid while manipulating the equation to isolate the variable.

Isolation of Variables

Isolation of the variable is the process of rearranging an equation so that the variable of interest stands alone on one side, making it easier to determine its value. This involves using inverse operations to eliminate any constants or coefficients attached to the variable.
