Its a square.
So 5n = n + 16
Therefore 4n = 16 (taking one n from each side).
So n = 16/4 which is simplied as : 4.
Double check by putting 4 in the equation where n is, and it makes sense, so that is the right answer.
Your answer is c.
I agree! The answer would be C the others don't make sense when worked out
