Key Concepts

Linear Equation

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. These equations graph as straight lines and are solved by finding the variable value that makes the equation true.

Combining Like Terms

This method involves adding or subtracting terms that have the same variable component in order to simplify an algebraic expression. It is an essential step in reducing equations to a simpler form.

Isolating the Variable

This technique involves performing operations on both sides of an equation to get the unknown variable alone on one side. It is a fundamental process in solving equations, ensuring that the solution satisfies the equality.
