Xiaoming found a contradiction in solving the problem: when he solved the inequality - x > x, he divided both sides of the inequality by X to get - 1 > 1, which is obviously wrong,

Dividing both sides of the inequality by X must satisfy that x is not zero
And if both sides of the inequality are divided by negative numbers at the same time, both sides need to change sign
In fact, this question should be
-10> X is 2x
