# Find A Solution That 'Set'isfy The Problem...

$$P$$ is a set containing $$6$$ elements. A subset $$A$$ of $$P$$ is chosen and the set $$P$$ is reconstructed by replacing the elements of $$A$$. Now a subset $$B$$ of $$P$$ is chosen again.

If the number of ways of choosing $$A$$ and $$B$$ such that $$B$$ contains just $$1$$ element more than $$A$$ is $$x$$

And

The number of ways of choosing $$A$$ and $$B$$ such that $$B$$ is a subset of $$A$$ is $$y$$.

Find $$y - x$$
