4x -y +z = 7 2a) Write the linear equation: 4x - 3y +z = -21. Can we use Jacobi iteration procedure to -2x + y + 5z = 15 solve it, for example, with the initial guess of (x, y, z) = (1, 2,2)? (A) Yes, this system satisfies Strictly Diagonal Dominant condition. (B) No, this system does not satisfy Strictly Diagonal Dominant condition. (C) Can't determine, depends on the choice of the initial guess (D)None of the above. Answer: 2b) Write a short explanation for your answer in 1) (above) (14 points)
