Key Concepts

System of Equations

A system of equations is a set of equations that are solved together, where the solution is the set of variable values satisfying every equation in the system. Understanding systems of equations is crucial for determining where different conditions or constraints intersect.

Substitution Method

The substitution method involves solving one of the equations for one variable and then substituting that expression into another equation. This technique reduces the system to a single equation with one variable, making it easier to solve.

Linear Equations

Linear equations are equations where each term is either a constant or the product of a constant and a single variable. Recognizing linear equations is important because their graphs form straight lines, and the point of intersection of these lines represents the solution to the system.
