Final Answer:
The accurate conclusion regarding the system of equations is option C: The only solution is the ordered pair (1, 3).
Step-by-step explanation:
Option C is correct because it represents the point of intersection between the two equations, which is the unique solution for the system. Substituting x=1 into both equations yields y=3, confirming the ordered pair (1, 3) as the solution. This conclusion aligns with the nature of a consistent and independent system where two distinct lines intersect at a single point. Options A and B are inaccurate since they suggest either no solution or infinitely many solutions, which doesn't hold true in this case. Option D is incorrect as it provides a different ordered pair not consistent with the system's solution.
