If you are familiar with systems of linear equations, it might be useful/interesting to you to know another approach.


<pre>
Let  "x" be the length of the way "to there" (in miles) and "y" be the length of the way back. Then

y + x = 200,
y - x =   8.

Add the two equations (both sides). You will get

2y = 200+8  --->  2y = 208  --->  y = {{{208/2}}} = 104.

Then x = y - 8 = 104-8 = 96.

<U>Answer</U>.  96 miles "to there" and 104 miles back.
