![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. 2x1 + 2x2 + 4x3 = 8 -6x1 - 6x2 - 12x3 = -24 -5x2 + 10x3 = 10 2x1 + 2x2 + 4x3 = 0 -6x1 - 6x2 - 12x3 = 0 -5x2 + 10x3 = 0 Describe the solution set, x = [x1 x2 x3] of the first system of equations in parametric vector form. Which option best compares the two systems? A. The solution set of the first system is a line parallel to the line that is the solution set of the second system. B. The solution set of the first system is a line perpendicular to the line that is the solution set of the second system. C. The solution set of the first system is a plane parallel to the plane that is the solution set of the second system. D.
