Question 21 • Advanced Algebra: Concepts and Connections
The matrix equation represents 6x + 4y = 1 and 9x + 6y = 3. The left side of the second equation is 1.5 times the left side of the first, so the right side would also need to be 1.5 times 1, or 1.5. Instead, it is 3, so the equations contradict each other. Therefore, the system has no solution (choice D).
