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