Let x be the answer.
Given that x is:
- Associated with a baroque painter and an ungulate
- A possibility to be faced by half of us
- Similar in sound to having been served a beverage
And the following equation holds true:
(x - DROPLET) + (x - MINSTREL) + (x - CANIFORM_CREATURE) = RAINBOW_EDGE
Solve for x and explain the clues.
