13. Consider the linear system of equations x1 + x2 + a3 = 9 2x1 – 3x2 + 4xs = 13. 3x1 + 4x2 + 5x3 40 %3D Then the solution (x1, x2, xs) (A) does not exist (B) satisfies a1 · az 3 = 12 (C) satisfies a1 • a2• 23 = 0 (D) satisfies a1 • x2 • 23 = 3/2 (E) satisfies x1 : x2 • 23 = 15 (Note: a a2 æz is the product of the components x1, az and as.)
