Systems of Linear Equations

Linear equations are equations that contain one or more variables and are of the first degree, meaning that the highest exponent of any variable is 1. Systems of linear equations are sets of two or more linear equations that are solved simultaneously. These systems are ubiquitous in mathematics and science and occur in various disciplines, including physics, engineering, economics, and finance. From the simplest linear equation such as 3x+4=10 to more complex systems of equations, these essential mathematical tools are ubiquitous in problem-solving.

What are Systems of Linear Equations?

At their core, systems of linear equations represent scenarios that involve multiple relationships between variables. Each equation in the system reflects one of these relationships; when solved collectively, they provide a comprehensive understanding of the entire situation. Solving systems of linear equations involves finding the values of the variables that satisfy each equation simultaneously.
