Battery Puzzle in Alan Wake 2 Solution

To get to the Cult Stash in Downtown Watery, you will first need to solve a puzzle. Unfortunately for math-haters, this one involves algebra. But luckily, you won’t have to do any arithmetic as we have the solution right here for you.
The solution to the Battery Puzzle in Alan Wake 2 is 496. If you’re curious as to how the math works, keep reading. If not, simply enter this code into the three spaces in the combination lock and you will get the rewards inside the Cult Stash.
The three batteries in the puzzle can be written as B1, B2, and B3. They have a total charge of 1600 amps. B1 is twice as much as B3 and B2 is 128 more than B3, so we arrive at the following equations:
- B1+B2+B3=1600
- B1=2B3
- B2=B3+128
Taking B3 as x, we get the equation: 2x+x+128+x=1600. Solving, we get x=368. Thus, B3 is 368, and as we know, B2 is 128 more than B3, so B2=368+128=496.
