Verified Answer :

the answer is nj+k=p


-m-3=p

8.)   n = \(\frac{p - k}{j}\)   Multiply both sides by j
      nj = p - k    Add k to both sides
 nj + k = p         Use the Transitive Property to flip the sides
       p = nj + k

9.) \(\frac{p + 3}{m}\) = -1   Multiply both sides by m
     p + 3 = -m   Subtract 3 from both sides
           p = -m - 3
