Answer:

C. x = 2 1/3, y = 1 1/3.

Explanation:

To solve this question, we need to plot the two equations on the graph and see where they cross. The graph below shows the two lines in different colors:

  • We can see that the point of intersection is somewhere between (1, 2) and (2, 1). Looking at the given options, we can see that only one of them is in that range. That is option C. x = 2 1/3, y = 1 1/3. Therefore, the answer is C. x = 2 1/3, y = 1 1/3.
