the second problem is let imagine you create the code for him (its impossible but let's imagine) he need time to run that code , it's like Pollard Kangaroo that needs months to solve the difficulty up to 100bit. So it's just don't waste your time.
equation with 2 variables has infinity solutions , you have to brute-force all of those solutions, may you need 33year to done
Lol. Cheap fuck
He could of offered at least 10 if the reward is 30 xD
