Final answer:
The given expression is already simplified and can be rearranged to -3x + xy + 6 - 2y. However, it cannot be further simplified without knowing the values of x and y.
Step-by-step explanation:
The expression given in the question is 6 - 3x - 2y + xy. While it already seems to be simplified, we can rearrange the terms to group the same variables together which would look like this: -3x + xy + 6 - 2y. In this case, we cannot further simplify this equation because we do not know the values of x and y. Each term contains either x or y, and we cannot add or subtract these from each other if they contain different variables. It's similar to how you cannot add apples to oranges.
