In order to solve the given equation above, what we are going to do is just to simplify it first. So, add or minus the values with common units. 9x + 7x and +26 - 17, so this would be 16x + 9. Next, 2x + 5x - 3x would be 4x. So the final answer would be 16x + 9 = 4x. The answer is the second option. Hope this explanation helps. Let me know if you need more help next time.
