The equation for the answer to the art problem is rather simple but impossible to achieve in a single lifetime, it is as follows: (x+y)(infinite) = z.

X= the art question,
Y=the art created in response to the question,
Z = the answer to the art problem.

Even when the art that has been created answers the given question, more questions are provoked by the art created, yielding an infinite number of questions to be answered through the art form.
