To solve:
|x+6|>0
General strategy to solve the inequalities that involve absolute value:
Absolute value inequalities deal with the inequalities (<,>,,and) on the expressions with absolute sign.
General properties for solving inequalities that involve absolute value are
1) |x|>k is equivalent to x<k or x>k, where k is positive number.
2) |x|<k is equivalent to xk and x<k, where k is a positive number and we can write a conjunction such as xk and x<k in the compact form k<x<k.
If k is a non positive number, we can determine the solution sets by inspection.

Calculation:
To solve: |x+6|>0
The given equation is of the form of |x|>k.
From the property we know that |x+6|>0 is equivalent to x+6<0 or x+6>0
First we have to isolate the absolute value expression on one side of the inequality before solving the inequality, so we have to subtract 6 from both sides.
x+6<0 x+6>0
x+66<06 or x+66>06
x<6 x6
The solution is x<6 or x6
The solution set is (,6)(6,)
Conclusion:
The solution set is (,6)(6,)
