Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
See later post. 
K = 2C  9d/8.
9d/8 + K = 2C,
9d/8 = 2C  K,
Multiply both sides by 8:
9d = 16C  8K,
Divide both sides by 9 and get:
d = (16C  8K) / 9.
