| x+5 | > 2 means: x+5 > 2 or x+5 < -2
then you solve it:
x+5 > 2 ---> x > -3
or
x+5 < -2 ---> x < -7
Answer: x > -3 or x < -7

Ther is not much work to show here. X cannot be equal to -3,-4,-5,-6,-7. The result will give you 0, 1, or 2. So X can be any number besides those.

If
|x+5| > 2
then:
x+5 > 2
x+5 -5 > 2-5
x > -3
and:
-x-5 > 2
-x-5+5 > 2+5
-x > 7
x < -7
therefore:
- infinity < x < -7 and -3 < x < + infinity

x+5>2
x>-3 or
x+5>-2
x>-7
as we see the no.line, from the two solutions, for the given problem solutions are many i.e., a real no. greater than -3 is the answer
