Looks like it. Try subtracting |x| from both sides, and also try plugging in a few values for x. Try a few like -50, 0, and 50, just to convince yourself.
| x | + 2 > | x | --------------- | x | is a non-negative number. So, when you add it to 2, that non-negative number will always be greater than the non-negative number itself. So, | x | + 2 > | x | always for real numbers x.
This would be true regardless of |x| being a non-negative number (eg. x + 2 > x) - it's just adding the same real number to both sides of an inequality, so it's really just saying 2 > 0, or that any real number plus two is greater than said real number.
