KUDOS
vannu, I wonder whether this question has something like "x could be...."

Because usually when we have inequalities we have a range of values.

This is what I did:

Resolving the first part $$2x>x+10$$
$$2x-x>10$$
$$x>10$$
This is the solution. Any value major than 10

Nor for the second part $$x+10>-x$$
$$2x >-10$$
$$x>-5$$
This is the solution. Any value major than -5.

As we must attend both situations at the same time, we need to intersect the solutions.
This means that the final solution is $$x>10$$

So, there is no a single value of x. Any value major than 10 will attend the equation.

PS.:Am I right? If yes, consider a kudo I am trying to sum kudos to access the tests.
