l 9 m 9 n
x
x =

Explanation:

Step1: Identify segment - addition

The length of line segment $LN$ (represented by $x$) is the sum of the lengths of $LM$ and $MN$.
$x=LM + MN$

Step2: Substitute given values

We know that $LM = 9$ and $MN=9$.
$x=9 + 9$

Step3: Calculate the sum

$x = 18$

Answer:

$18$
