Sure. Schnorr signatures take a nonce `k` and a challenge `e` and produce a signature by computing:
s = k + e*a
, where a is the private key of the signer and the number we want to find.
The problem gave 2 signatures, which give a ssytem of linear congruences:
s_1 = k_1 + e_1*a (mod p)
s_2 = k_2 + e_2*a (mod p)
Since we know that the difference between k_2 and k_1 is 7, the system is suddenly determined and we can subtract equation 2 from equation 1:
s_2 - s_1 = k_2 - k_1 + e_2*a - e_1*a (mod p)
Now we know k_2-k_1 so:
s_2 - s_1 = k_delta + e_2*a - e_1*a (mod p)
And solve for a:
a = (s_2-s_1 - k_delta) * (e_2-e_1)^-1 (mod p)
Where ^-1 is the modular inverse.

Thanks for posting. I used similar approach but somehow got formula wrong
This seems too wild to be true
I figured something like that, but from what I can tell your diet contains a TON of varied mushrooms! Way more than most.
How many mushrooms do you eat man?
Had to look up who that was, but agree with your sentiment. Have been wanting to educate myself about this period in history lately.
Same issue on phone but loaded fine on another device
If you haven't read what Ross wrote at the end of the year, you should.

Hard agree. According to nic Carter’s best guess, my dig was very heavily held back with pause orders and ocp2.0 stuff. There are new documents coming out very recently (finally). Big comeback arc for Ross building
Getting tix to see nosferatu movie tomorrow 😈
Ok, I had to know why I was confused. There was some (unrelated?) other guy named Joey Saladino who I had him confused with. Don’t wanna spread disinformation 😅
Coolest novelty slippers I’ve seen in a while
I had to ask because I swear there was a guy doing these edgy things in rough neighborhoods to expose “reverse racism” and a vid came out showing it was staged… but I could be waaay off on who it was 🤦♂️ might have been on Vine 😂
Am I remembering wrong or didn’t Saladino stage some sort of stunt where he got beat up by black people, which later got revealed? I could be way off, don’t follow him at all
