KarishmaB · Answer

To remove the absolute value sign from an equation/inequality, we can use the definition of absolute values:

|x| = x if x >=0 
|x| = -x is x < 0

So if x is negative, |x| = -x and |x| + x will become -x + x which is 0. 
If we need it to be greater than 0, x should be positive.

Option (A) satisfies.

KSBGC · Answer

Only positive value works here.

|x| is always positive but only x is negative for negative value. So, ultimate result is 0.

The best answer is A.

mandy0rhtdm · Answer

For x > 0 this equation is always positive
For x < 0 this equation is always zero 
So only answer greater than zero is 2
