    Answer:

      y = 0

    Step-by-step explanation:

    Subtracting the right side gives …

      \dfrac{y}{P-9}-\dfrac{y}{P+9}=0\\\\y\left(\dfrac{(P+9)-(P-9)}{P^2-81}\right)=0\\\\y\left(\dfrac{18}{P^2-81}\right)=0\\\\\boxed{y=0}

    The factor multiplying y cannot be zero, so y must be zero.
