Re: Codebusters C

Here's an excerpt from the lab I did in chem class today, encoded as a Caesar cipher:

Ze kyzj vogvizdvek, pfl nzcc jklup kyv vwwvtk fw zetivrjzex kyv tfetvekirkzfe fw re zfezt tfdgfleu fe tfeultkzmzkp.
`shift = 17`
`IN THIS EXPERIMENT, YOU WILL STUDY THE EFFECT OF INCREASING THE CONCENTRATION OF AN IONIC COMPOUND ON CONDUCTIVITY.`
Solve this following affine:
YOIMDOMCFSEBIQN
Where N=D and D=N
(It may appear at first that the question is unsolvable due to the a value not being coprime to 26, but the question is actually solveable).
Edit: also something interesting- the encryption key and decryption key are the same.

There may be an issue solving here due to the April Fool's thing.
If life gives you melons, you're dyslexic.

Why can't dinosaurs ski? Because they're dead.

thewe may be an issue solving hewe due to the apwiw foow's thing.
I doubled checked, it should work. However, I edited my post bc there are some details i forgot to mention oops
