B is the midpoint of line segment AC. 
If AB = 3x - 8 and BC = x + 12, find the value of x.
~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Since B is the midpoint, we have AB = BC.


It is the same as this equation

    3x - 8 = x + 12.


Simplify and find x

    3x - x = 12 + 8

      2x   =   20

       x   =   20/2 = 10.


<U>ANSWER</U>.  x = 10.
</pre>

Solved.
