    rearrange for z
    subtract 3i from both sides
    mod both sides

    Any good?

    on your last few lines when plugging x and y into the circle equation you forgot to square them

    ie you wrote  \displaystyle x + y = 6y instead of  \displaystyle  x^2 + y^2 = 6y

    Edit: Your method isn't as easy as the modulus method imo, if you get confident with using modulus for these questions transformations will be very very easy for you, trust me
