Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.

Here is how to calculate a determinant for both 2x2 and 3x3 matrices: A system of equations that is formed using a singular matrix has either 0 solutions or an infinite number of solutions. The only way to determine which of these is the case is to use the augmented matrix and simplify as long as possible.
