Answer:

(8, 72)

Step-by-step explanation:

Here we have two separate equations for y:  y = 9x and y = 2x + 56.

Equating these equations eliminates y temporarily; we get:

9x = 2x + 56, or 7x = 56.  Dividing both sides by 7 results in x = 8.  

Then, by the first equation, y = 9(8) = 72.

The solution is (8, 72).
