Answer:
-y=-x
The problem: 
 y=x then -y=?
Step-by-step explanation:
If y=x, then -y=-x.
Just like if u=9, then -u=-9.
Or, if -m=8, then m=-8.
 
        
             
        
        
        
If 81=n-3(-5+4n)
   81= n+15-12n
   81= -11n+15
   -11n=81-15
   -11n=66
   n=-6
        
                    
             
        
        
        
The answer to the question is n>1/2.
