What is a system of equations?

A system of equations is a collection of two or more equations that are solved simultaneously, meaning that their solutions satisfy all of the equations in the system. Each equation in the system represents a relationship between variables, and finding the solution to the system involves finding the specific values of the variables that make all the equations true at the same time. These systems can be algebraic equations, linear or nonlinear, or even a combination of different types of equations. The solutions to a system of equations can be unique, meaning there is a single set of values that satisfies all the equations, or they can be infinite, where there are multiple sets of values that satisfy the equations. System of equations are widely used in various fields such as science, engineering, economics, where they help model and solve real-world problems.
