Answer:
<h2>y = -5x - 10</h2>
Step-by-step explanation:

4(x + 9) + 5x = 9x - 36
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true.
So there is no solution for this equation.
Answer is C. no real solutions
I believe the answer is 5. Hope this was right for you.
