Question 979825: Hello. I am needing help with my ALgebra 1 class. I have tried basically everything I know how to but still keep failing my exams. (I'm home schooled) Please help me solve this equation +IF+%28n%2B9%29%3C4+THEN+n%2B9%3E-4+AND+n%2B9%3C4+
Please note the < actually mean less than, greater than or equal to but I couldn't find a way to input the dash under the <. Thank You!

You can put this solution on YOUR website!
|n+9| <= 4 means n+9 >= -4 and n+9 <= 4

Solve n+9 >= -4 for n to get n >= -13

solve n+9 <= 4 for n to get n <= -5

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

The solutions to |n+9| <= 4 are n >= -13 and n <= -5

We can condense that into -13 <= n <= -5

Note: ">=" means "greater than or equal to" and "<=" means "less than or equal to"
