The equation $x = 4$ is already solved, as it states that the value of $x$ is equal to 4. There are no further steps required.

Would you like details or have any related questions?

Here are some questions to deepen your understanding:

1. What is the significance of solving for $x$ in algebra?
2. Can equations like $x = 4$ be represented graphically?
3. How does a simple equation like $x = 4$ differ from more complex equations?
4. What does $x$ represent in the context of real-world problems?
5. How would this equation change if we added constraints, like $x > 4$?

Tip: Always check the context of an equation to ensure the solution makes sense for the given scenario!
