3n+9+4>-4n+4
Use the distributive property to multiply 3 by n+3.
3n+13>-4n+4
Add 9 and 4 to get 13.
3n+13+4n>4
Add 4n to both sides.
7n+13>4
Combine 3n and 4n to get 7n.
7n>4-13
Subtract 13 from both sides.
7n>-9
Subtract 13 from 4 to get -9.
n>-\frac{9}{7}
Divide both sides by 7. Since 7 is positive, the inequality direction remains the same.
