A student solved a 3×3 matrix using Cramer's rule. If Dx = 0, Dy = 0, Dz = 0 and D ≠ 0, what is the solution? A. No solution B. x=1, y=1, z=1 C. Infinite solutions D. x=0, y=0, z=0 Answer: D) x=0, y=0, z=0 Explanation: By Cramer's rule, x = Dx/D = 0/D = 0. Similarly, y = 0 and z = 0. This is the trivial solution.
