Understanding Linear Equations

A linear equation in two variables (x and y) represents a straight line on a graph. A system of two linear equations involves two such equations. Solving this system means finding the point (x, y) where both lines intersect, if they do. This point is the solution that satisfies both equations simultaneously. Methods to solve include substitution, elimination, and graphical methods. This tool uses matrix methods for efficient solutions and visualizes the equations and their intersection point on a graph using Plotly for better understanding. Linear equations are fundamental in mathematics and have applications in various fields like physics, economics, and computer science.
