Answer:


\Huge \boxed{N<9}

Explanation:

To solve this problem, first you have to isolate it on one side of the equation. Subtraction property of equality is subtract from both sides of an equation the same number doesn't change the equation.

First, subtract 4 from both sides.


\displaystyle n+4-4<13-4

Solve.


\displaystyle 13-4=9

In conclusion, the correct answer is n<9.
