A system of equations (also known as simultaneous equations) is a set of equations with multiple variables, solved when the values of all variables simultaneously satisfy all of the equations. The most common ways to solve a system of equations are: The graphical method; The substitution method; The elimination method

- Using the Substitution Method. Download Article 1 Move the variables to different sides of the equation. This "substitution" method starts out by "solving for x" (or any other variable) in one of the equations.
- Using the Elimination Method. Download Article 1 Find the variable that cancels out. Sometimes, the equations will already "cancel out" a variable once you add them together.
- Graphing the Equations. Download Article 1 Only use this method when told to do so. Unless you are using a computer or graphing calculator, many systems of equations can only be approximately solved using this method.

- Introduction to Systems of Equations. In order to investigate situations such as that of the skateboard manufacturer, we need to recognize that we are dealing with more than one variable and likely more than one equation.
- Solving Systems of Equations by Graphing. There are multiple methods of solving systems of linear equations. For a system of linear equations in two variables, we can determine both the type of system and the solution by graphing the system of equations on the same set of axes.
- Solving Systems of Equations by Substitution. Solving a linear system in two variables by graphing works well when the solution consists of integer values, but if our solution contains decimals or fractions, it is not the most precise method.
- Solving Systems of Equations in Two Variables by the Addition Method. A third method of solving systems of linear equations is the addition method. In this method, we add two terms with the same variable, but opposite coefficients, so that the sum is zero.
To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that will satisfy all equations in the system at the same time. Some linear systems may not have a solution and others may have an infinite number of solutions.
To solve a system of two linear equations, we want to find the values of the variables that are solutions to both equations. In other words, we are looking for the ordered pairs (x, y) that make both equations true. These are called the solutions of a system of equations.
