Let -2] A = and b = 2

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 below. 3x₁ + 3x₂ +6x3 = 12 - 9x1 - 9x2 - 18x3 = - - 36 - 6x2 - 18x3 = 18 Describe the solution set, x = O of the first system of equations in parametric vector form. Select the correct X2 X3 choice below and fill in the answer box(es) within your choice. (Type an integer or fraction for each matrix element.) O A. X= B. X=X₂ C, X= D. X=X₂ + X3 3x₁ + 3x₂ + 6x3 = 0 - 9x1 - 9x2 - 18x3 = 0 - 6x2 - 18x3 = 0 + X3

−24x  −  16y  +  16z  =  16 −12x  +  4y  +  32z  =  32 4x  −  12y  −  32z  =  −32 Enter the solution as an ordered triple. For parametric solutions use  z = t  as the parameter.
