Adding and Subtracting Rational Expressions

there are two problems I get stuck with towards the end.

1) 5n/3 + 4n/3
5n+4n/3
9n/3

now i get stuck, i think that I must factor it more but i am unsure, my teacher said I incorrectly distribute the signs?

2) 7/x-5 - 2+x/x-5
for this one I get an answer of -1

1) 5n/3 + 4n/3 = 9n/3
9n/3 = 3n

2)7/(x-5) - (2+x)/(x-5) = (7-2+x)/(x-5)
= (5+x)/(x-5)
