Here is what I think. Since the line creates midpoints which divide AB and BC evenly, we have a 1:2 ratio for side lengths BD and BA as well as BE and BC.

anonymous · Answer

Knowing that, we see that we have similar triangles, and can also say that side DE must be 1/2 of AC.

anonymous · Answer

DE=AC*1/2

anonymous · Answer

Thus 2x+1=15
x=7.
Don't take my word for this, I haven't done geometry in almost 3 years.
