It appears as if there is no solution.

#### Explanation:

Since we cannot get y explicitly as a function of x, we use implicit differentiation.

Differentiate both sides, bearing in mind that y is a function of x, and then solve for

This seems to indicate the impossible fact of

Hence there is no solution.
