1. **State the problem:** We are given the system of equations:
$$xy = x^x$$
and
$$y = 9$$
We need to find the value(s) of $x$ that satisfy both equations.
2. **Substitute $y=9$ into the first equation:**
$$x \cdot 9 = x^x$$
which simplifies to
$$9x = x^x$$
3. **Rewrite the equation:**
$$x^x = 9x$$
4. **Analyze the equation:**
We want to find $x$ such that $x^x = 9x$.
5. **Check for $x=0$:**
Not valid since $x^x$ is undefined at $x=0$.
6. **Check for $x=1$:**
$$1^1 = 1$$
$$9 \times 1 = 9$$
Not equal.
7. **Check for $x=3$:**
$$3^3 = 27$$
$$9 \times 3 = 27$$
Equal, so $x=3$ is a solution.
8. **Check for $x=9$:**
$$9^9$$ is very large, while $$9 \times 9 = 81$$
Not equal.
9. **Check for $x=0.5$ (for completeness):**
$$0.5^{0.5} = \sqrt{0.5} \approx 0.707$$
$$9 \times 0.5 = 4.5$$
Not equal.
10. **Conclusion:** The only solution is $x=3$.
**Final answer:**
$$x=3, y=9$$
