abs%28x%2B7%29%3E5 Start with the given inequality


Break up the absolute value (remember, if you have abs%28x%29%3E+a, then x+%3C+-a or x+%3E+a)

x%2B7+%3C+-5 or x%2B7+%3E+5 Break up the absolute value inequality using the given rule




Now lets focus on the first inequality x%2B7+%3C+-5


x%2B7%3C-5 Start with the given inequality


x%3C-5-7Subtract 7 from both sides


x%3C-12 Combine like terms on the right side


Now lets focus on the second inequality x%2B7+%3E+5


x%2B7%3E5 Start with the given inequality


x%3E5-7Subtract 7 from both sides


x%3E-2 Combine like terms on the right side



----------------------------------------------------

Answer:

So our answer is

x+%3C+-12 or x+%3E+-2


which looks like this in interval notation
