To solve this problem, we have to use the definition of segment addition.

LA=PL+PA

Then, we replace the given expressions

30x-18=6x+24+12x-6

Now, we solve for <em>x</em>.

\begin{gathered} 30x-6x-12x=24-6+18 \\ 12x=36 \\ x=\frac{36}{12} \\ x=3 \end{gathered}<h2>Hence, x = 3.</h2>

Let's find LA:

30x-18=30\cdot3-18=90-18=72<h2>Hence, LA measures 72 units.</h2>
