f%28x%29=%289%2F%28x-16%29%29%2B%288%2F%28x%2B10%29%29+=+0+

9%2F%28x-16%29%2B8%2F%28x%2B10%29+=+0 .........solve for x



%289%28x%2B10%29%2B8%28x-16%29%29%2F%28%28x%2B10%29%28x-16%29%29+=+0

%289x%2B90%2B8x-128%29%2F%28%28x%2B10%29%28x-16%29%29+=+0

%2817x-38%29%2F%28%28x%2B10%29%28x-16%29%29+=+0...........this will be equal to zero only if numerator equal to zero

17x-38=+0

17x=38

x=38%2F17
