Find Center and Radius of Circle For This Equation

The equation is: x^2 +16x +105/16 +4y^2 +3y = 0

I do not see how to get rid of the coefficient on y^2 without introducing a
coefficient on x^2.

I was able to manipulate this toget : (x + 8)^2 + 4(y +3/8)^2 = 58
but I don't see how that helps. I feel I must be missing something or
perhaps the problem should have had a 4x^2 factor? Thanks in advanc efor
any advice on how to solve this.
