Well you solve the equation then find out what you dealing with
        
             
        
        
        
-8=-(x+4)
remember the invisible 1
-8=-1(x+4)
distribute using distributeiv porpety
a(b+c)=ab+ac
-1(x+4)=-x-4
-8=-x-4
add 4 to both sides
-4=-x
mutily both sides by -1
4=x
        
                    
             
        
        
        
The answer of this problem is
