Extracted text: Describe the solutions of the first system of equations below in parametric vector form. Provide a geometric comparison with the solution set of the second system of equations shown below. X1 - X2 + 3x3 = 6 X1 - X2 + 3x3 = 0 X1 2x, + X2 + 3x3 = 9 2x, + X2 + 3x3 = 0 where the solution set is x =| x, - X, - 2x2 = -3 -x, - 2x, = 0 X3 Describe the solution set of the first system of equations in parametric vector form. Select the correct choice below and fill in the answer box(es) within your choice. (Type an integer or fraction for each matrix element.) O A. X = O B. X=X2 Oc. x= + X3 O D. X=X2 + X3
