There is no algebraic way to solve this, but you can plug in each answer choice for x.
Notice that when x = 2 (choice A), y = 3^x becomes y = 3^2 = 9
Also, when x = 2, y = 7x - 5 becomes y = 7(2) - 5 = 14-5 = 9
So when x = 2, y = 9 for both equations.
So the answer is choice C) 9 because they want the y value of the solution.
