You can put this solution on YOUR website!
abs%28x%2B5%29%3E12 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%2B5+%3C+-12 or x%2B5+%3E+12 Break up the absolute value inequality using the given rule




Now lets focus on the first inequality x%2B5+%3C+-12


x%2B5%3C-12 Start with the given inequality


x%3C-12-5Subtract 5 from both sides


x%3C-17 Combine like terms on the right side


Now lets focus on the second inequality x%2B5+%3E+12


x%2B5%3E12 Start with the given inequality


x%3E12-5Subtract 5 from both sides


x%3E7 Combine like terms on the right side

Answer:

So our answer is

x+%3C+-17 or x+%3E+7


which looks like this in interval notation





if you wanted to graph the solution set, you would get
