One website calls it the sidesplitter theorem, but that seems to be just his name for it. Google <triangle parallel lines> and you will find several discussions of the topic.

That means 8 is 2 times bigger then X
so 8/2=4=x"

That works and can be derived from the attributes of similar triangles.

"I also found it work if we only knew the bottom one by changing it a little like this.
2x8=X=16 (simply changing the "divide by 2" into "multiply by 2")"

I don't understand what you're trying to say in that paragraph.
