A matrix is a compact grid or array of numbers It can be created from a system of equations and used to solve the system of equations Matrices have many applications in science engineering and math courses This handout will focus on how to solve a system of linear equations using matrices How to Solve a System of Equations Using Matrices Using the Matrix Calculator we get this I left the 1 determinant outside the matrix to make the numbers simpler Then multiply A 1 by B we can use the Matrix Calculator again And we are done The solution is x 5 y 3 z 2 Just like on the Systems of Linear Equations page

One of the most commonly used applications of square matrices is solving systems of linear equations The methods of solving systems of linear equations using matrix algebra are much more efficient than hand calculating the systems using substitution This is especially true when dealing with systems of 3 or more variables Two methods of Performing Row Operations on a Matrix Now that we can write systems of equations in augmented matrix form we will examine the various row operations that can be performed on a matrix such as addition multiplication by a constant and interchanging rows Performing row operations on a matrix is the method we use for solving a system of equations
