Create a program to solve the following equation.
To solve the given equation `x + y = 6`, we need to express one of the variables in terms of the other. Here's one way to do it:
```
Given: x + y = 6

Subtract x from both sides of the equation to isolate y: 

x + y - x = 6 - x

After simplification, this becomes: 

y = 6 - x
```
This solution, `y = 6 - x`, expresses the value of `y` in terms of `x`. However, since we have two unknowns in this equation, we cannot have a single unique solution for both the variables `x` and `y`. Instead, we have multiple valid solutions that satisfy the constraint set by the given equation. If we have more information about the value of `x` or the value of `y`, we could further solve for a unique solution for both variables.
x + y = 6
