To solve for $x$ in the equation $y = x + 6$:

1. Start with the given equation: $y = x + 6$

2. Subtract 6 from both sides to isolate $x$: $x = y - 6$

Thus, the solution is: $x = y - 6$

Would you like more details, or do you have any questions?

Here are some related questions:

1. If $y = 10$, what is the value of $x$?
2. How would you graph the equation $y = x + 6$?
3. What is the slope of the equation $y = x + 6$?
4. How would the equation change if the constant was different, say $y = x + 4$?
5. Can you express $x = y - 6$ in terms of other variables?

Tip: Always check your solution by substituting it back into the original equation.
