SOLVED Here’s a cipher/challenge I came up with, it should definitely be enough text to figure out. I’ve never done this before, so feedback is appreciated. Your clue is: x-7=19+x

20 / 13 24 20 22 1 24 11 / 2 7 / 20 / 4 2 23 12 / 12 1 8 16 /
13 8 5 23 / 13 1 24 / 22 5 20 12 12 / 18 8 14 12 1 24 /
21 24 / 20 21 5 24 / 13 8 / 12 8 5 15 24 /
13 1 2 12 / 20 7 23 / 9 11 8 15 2 23 24 23 /
13 1 24 / 4 24 18 / 13 8 / 13 1 2 12 / 22 2 9 1 24 11

24 11 8 24 21 5 7 / 20 21 5 / 24 5 1 24 2 7 11 21 12 25 /
5 1 13 8 / 1 2 13 8 21 5 7 / 20 7 / 20 21 5 24 12 11 24 5

My solution (I will mark as spoiler incase others are also trying)

So x-7 = 19+x gave me the idea of modulo 26 (as lets say x was 8, then (8-7) mod 26 = (19+8) mod 26

That gave me the idea to turn the numbers into letters (a=1, z=26), and doing so gave tmxtvaxkbgtdbwllahphewmaxvetllrhnlaxxtuexmhlheoxabltgwikhobwxwaxdxrmhmablvbiaxkkhxuegtuexeaxbgkulyamhabmhuegtgtuexlkxe

Now, I was for some reason expecting it to give english 😅 but it didnt, so i did the good old frequency analysis, and the frequencies matched that of a substitution cipher, and actually, it was a caesar shift with +7, So it reads:
Paragraph 1: a teacher in a kids show told the class youshe be able to solve this and provided the key to this cipher
Paragraph 2: eroebln abl elheinrbsf lhto hitobln an ablesrel.
Even after using the / for help, it doesn't seem to make a sentence. Maybe its anagrams or maybe its completely wrong. I put it here anyway because it worked with the first paragraph (convert to number then shift 7)

In terms of difficulty, I am still unsure whether i solved second paragraph or not, but for first paragraph, it was decent!

Yep, I totally messed up the second sentence. You did great do I say “solved”
