Question 182584
Solve the following inequality. Write the answer in interval notation. Note: If the answer includes more than one interval write the intervals separated by the "union" symbol, U. 
Problem : 
4|x+4|-1<6

-------------------
4|x+4| < 7

|x+4| < 7/4

-7/4 < x + 4 < 7/4

-4-7/4 < x < -4+7/4

-23/4 < x < -9/4
-------------
Interval notation:
(-23/4, -9/4)
