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

    Hi there!  

    »»————-　★　————-««

    I believe your answer is:  

    y = 3

    »»————-　★　————-««  

    Here’s why:  

    ⸻⸻⸻⸻

    \boxed{\text{"The value of 9-y twice as much as the value of y" can be written as:}}\\\\9-y = 2y

    ⸻⸻⸻⸻

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

    ⸻⸻⸻⸻

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