Answer:
{x I - 12 < x < 7}
Step-by-step explanation:
Fuaad solved an absolute value inequality and expressed the solution as - 12 < x < 7.
So, the value of x lies between - 12 and 7 but not including - 12 and 7.
Option C will give another way to show Fuaad's solution.
It is {x I - 12 < x < 7}, which means x is a variable which belongs with in the interval (- 12, 7). (Answer)
