Key Concepts

System of Linear Equations

A system of linear equations consists of two or more linear equations that involve the same set of variables. The goal is to find values for these variables that satisfy all equations simultaneously. This concept is fundamental in algebra and is used in contexts ranging from basic problem solving to advanced applications in mathematics and engineering.

Substitution Method

The substitution method is a technique for solving a system of equations where one equation is solved for one variable in terms of the others, and then this expression is substituted into the other equation(s). This method simplifies the process by reducing the system to a single equation with one unknown, making it easier to solve for the variable before back-substituting to find the remaining variable(s).
