Can someone help me with this? logical problem

I think it's E because

2 times what gives you 14? 7.

10 + what gives you 17? 7.

Therefore, E must be the right answer.

It seems to be the solution but it's very contrived imo. I wouldn't have thought to reason in circles with a triangle based problem.

I think E is the right answer, but for my solution.

I think it makes sense because they arranged them in that way, instead of just putting 3 triangles side by side

Yo what do you think of my solution?

Guys, what about this one?

My best guess is A. It looks like a 2x2x2 Rubik's Cube btw.

5 is on the bottom right and upper right, so 9 must be on the upper left and, since 9+3 is 12, with only A, C,, E, and F having double digits on the bottom, my best guess is A.

Oh, and 6x2 also gives 12.
