Y=3 because 9-3=6 and 3*3=6

Hi there!

I believe your answer is:


y = 3

Here’s why:

⸻⸻⸻⸻


\boxed{\text{

⸻⸻⸻⸻


\boxed{\text{Solving for 'y'...}}\\\\9-y=2y\\------------\\\rightarrow 9 -y + y = 2y + y\\\\\rightarrow 9 = 3y\\\\\rightarrow (9=3y)/(3)\\\\\rightarrow 3 = y\\\\\rightarrow \boxed{y = 3}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
