Inverse Matrix Method The inverse matrix method is a method of solving an unsolved system of equations by using a matrix and the formula AA=I and AX= B to find the solution to the variables where I is the identity matrix. Start with your unsolved linear system. You must make sure that you have an equal number of variables and equations or the method won?t work. Line the coefficients up in a matrix by system. For example, If your systems were: -1x + 1y + 3z = 2 -1 1 3 x 2 2 x + 1y +2z = 2 then you would arrange it as 2 1 2 y 2
