    Move everything to one side, multiply both sides by z, and solve the quadratic.

    It may not come up, but it's important to remember when you do this that z cannot equal 0.

    is it (z+8)/z or z + (8/z) on the left side?

    Ok, so when you multiply by z you get \[z^2 + 8 = -9z\]

    If you move the -9z to the other side you'll have a quadratic equation you can solve.
