Let's call the number x.
According to the problem, the following equation is true: 2x + (x-10) = -2-x
Simplifying this equation, we get: 3x - 10 = -2 - x
Adding x and 10 to both sides, we get: 4x = 8
Dividing both sides by 4, we get: x = 2
Therefore, the answer is D (2), as it satisfies the condition of the problem.
