Using the matrix notation, write the system of linear equations: 2x1 - X4 = -1 5x1 + X2 = 2 X3 = 1 -x1 +4x3 + x4 = 0 is the vector of variables. Then, find the system solution as: x = A-'b, and write the value of x2. (Hint: Use the Gauss-Jordan X3 as Ax = b, where x = algorithm to find the inverse A- of the matrix A first).
