Systems of Equations

Systems of linear equations involve multiple equations with multiple variables. The primary goal is to find the values of the variables that satisfy all equations in the system. There are several methods to solve systems of equations, with substitution and elimination being two of the most commonly used methods. 

Solving systems of equations is a fundamental skill in mathematics and has applications in various fields, including physics, economics, engineering, and more. It's essential for analyzing and understanding relationships between different variables and solving complex problems involving multiple unknowns.
