\[\left\lfloor x+\dfrac{1}{2}\right\rfloor +\lceil x \rceil+\left\lfloor x-\dfrac{1}{2}\right\rfloor\ge \left\lceil x+\dfrac{1}{2}\right\rceil+\lfloor x \rfloor+\left\lceil x-\dfrac{1}{2}\right\rceil\] Given that \(1\le x\le 1000\) is a real number, find the number of different \(x\)'s that satisfy the above inequality.
If you believe there are an infinite number of \(x\)'s that satisfy the inequality, then submit \(-1\).
