Solution?

There’s an (x - x) in there

Technically there is a (x - 𝑥) in there. U+1D465 != x so this post is a little meh

Mathematicians do weird stuff to get more letters, but I've never seen anyone use x and 𝑥 for different things

Yeah, me neither. I have had situations where I needed to distinguish between u, v, nu, and upsilon though. I had to be very careful with my handwriting that day...

They also wouldn't want to be ambiguous. If I was trying to write this problem the a, b, c... would get replaced by something like a_1, a_2,..., a_26 to be clearer. This problem works as a fun gotcha but isn't something that would come up in the real world.

the first variables aren't roman. they're italicized as well. idk where you're getting the x vs x thing.

Do do, do do do do do....

Assuming both x represent the same number. There's no reason to assume the ellipses should include x-x. Why would alphabetic order be involved at all?

have you never taken math? I'm seriously asking because you're incredibly wrong in both statements.
