Answer:
No! Both are wrong!
Step-by-step Explanation:
the value of absolute function, (|.|) is always positive 
that means -6x always has to be positive 
and for -6x to be positive x has to be negative 
(since, two negatives make a positive)
therefore, the value of x to the equation will be a negative value and not a positive one. 
 Ana thinks both positive and negative values of x will be the solution,  whereas Ling thinks negative value of x can't be a solution. So, they're both wrong. 
ONLY negative value of x will be the solution.
