SYSTEMS OF EQUATIONS Solving Using The Inverse Matrix (Page 1 of 4)

Let's solve the system of equations 2x-y+2z = -8; x+2y-3z = 9; 3x+11y-12z = 43 using an inverse matrix. To do this, write the system in the matrix form AX = B, where A is the coefficient matrix and B is a column matrix containing the constant terms. As long as matrix A is invertible (has an inverse), the solution of the system is given by the product A^(-1)*B.

First enter matrices A and B into the calculator. For this system, A = matrix{row1: 2 -1 2; row2: 1 2 -3; row3: 3 11 -12} and B = matrix{col1: -8 9 43}.
