Inverse of a 3 x 3 Matrix
You learned a trick to finding the inverse of a 2 x 2 matrix that makes solving systems of equations with two variables quite simple when using matrices. You can also solve systems of equations with three variables, and matrices are by far the easiest process to use.
Finding the inverse of a 3 x 3 matrix algebraically is not quite as simple as finding the inverse of a
2 x 2 matrix algebraically. Because of this, we are going to utilize technology to help us with the process.
You can use one of the following tools to help you with finding the inverse of a 3 x 3 matrix.
