Answer:  " n = - 4 " .
__________

Step-by-step explanation:

Given:
 -n + 8  = 12 ;  solve for "n" ;

Subtract "8" from each side of the equation:

-n + 8 - 8 = 12 - 8 ;

to get:
 -n = 4 ;

Which is the same as:
 -1n = 4 ;

Divide each side of the equation by "-1" ; to isolate "n" on one side of the equation; and to solve for "n" :

  -1n / -1 = 4 / -1 ;

 to get:
    " n = - 4 " ;  which is our answer.
_______________

Now, let's check our answer:
_______________
→ by plugging in our value obtained for "n" ; which is " - 4 " ;
_______________
-(-4)  +  8 ≟  12 ?? ;
_______________

From the "left-hand sign" of the equation:
_______________
 " - (-4) = ⁺ 4 " ;  
_______________
Note:  The opposite of negative value; or the negative of a negative value; is equal to that very positive value.
_______________
⇒ " 4  +  8  ≟  12 ? ;

⇒ " 12  ≟  12 ? ;   Yes!

_______________
The correct answer is:  " n = - 4 " .
_______________
