The answer is:
________________
n = ¼ ; or, write as: 
n = 0.25
______________________
Explanation:
__________________
-7 / (2n) = 49 ;
__________________
-49 * (2n) = -7 ; 
________________
Divide each side by "(-49)" ; to isolate the "2n" on one side, and to get rid of the "negative" values:
_____________________________
[-49*(2n)] / -49 = -7/ -49 ;   to get:
_______________________________
2n = (½);  Now, divide EACH side of the equation by "2"; to isolation "n" on                       one side of the equation, and to solve for: "n";
__________________________________________________
2n / 2 = (½) / 2 ;
