there is exactly ONE "machine" that causes your result to be incorrect. ONLY for part 2.

Button A: X+67, Y+67
Button B: X+16, Y+73
Prize: X=4877, Y=7214

I see now what your corner case causes. so when my script solves for y first. it will be exact. BUT when you solve for x, it will be not divisible... makes sense now. I didn't expect this. This only occurs because of part 2! so dastardly. well, that was interesting. I guess I am forced to add that extra check... rip those microsecond gains.
