Three liquids are at temperatures of 14 â—¦C, 25â—¦C, and 33â—¦C, respectively. Equal masses of the first two liquids are mixed, and the equilibrium temperature is 16â—¦C. Equal masses of the second and third are then mixed, and the equilibrium temperature is 27.9 â—¦C. Find the equilibrium temperature when equal masses of the first and third are mixed.

Answer in units of â—¦C.
