2 Answers
See a solution process below:
Explanation:
The absolute value function takes any negative or positive term and transforms it to its positive form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
Subtract
Or
Or, in interval notation:
Explanation:
If
So we can rewrite this problem as 2 equations:
#9+x<=7# and#9+x>=-7#
Now solve each equation and then use those to create your solution set.
#x<=7-9# and#x >= -7-9#
#x<=-2# and#x >= -16#
And finally, combine these two into a single equation which is your solution.
#-16<=x<=-2#
