How can we solve - 14n + 1 = rt - 4n for n

A possible answer can be n = 1/10 + rt/-10. I brought the - 4n over to the other side and the + 1 to the other side, giving me - 10n = - 1 + rt. I divided it all by - 10, which gave me n=-1/-10 + rt/-10. Since two negatives cancel each other out and becomes a positive, - 1/-10 becomes 1/10.
