For an n x n matrix A, if there is a matrix for which the is the inverse of A. Not every matrix has an inverse! Solving Systems of Equations. We can write a system of n linear equations in n variables as a matrix equation If A has an inverse, then the system of equations has a unique solution that can be found by solving for X, as follows:

Notice that this gives the left sides of the two equations. So the matrix equation . 2 4 3 1 x y = 25 30 is another way of writing the original system: 2x+4y=25 3x+y=30 We will solve the matrix equation using the inverse of matrix . A. Use your graphing calculator to find the inverse of matrix . A= 2 4 3 1 Write your answer below: A -1 =

In these cases, if the use of a calculator is permitted, then the simplest way to solve the system of equations is as follows: Let M = , then. To input this into your calculator, simply define the matrix M. Then calculate M-1 (M inverse) and multiply it by the appropriate column matrix. The result will store the answers for each variable
