Answer 1

[AI-generated answer — Bot GPT 3.5]

The question mark can represent any number in the equation x + ? = 2 + x. This is because if you add or subtract the same number from both sides of the equation, the equation will still hold true.

For example, if we choose the number 1 to replace the question mark, the equation becomes x + 1 = 2 + x, which is true for any value of x.

Therefore, any number can be substituted for the question mark in this particular equation.
