You have the math right, "in theory," but the problem is that
"in real life" you can't control how much your body burns, and eating less can trigger burning less.
Starvation mode is mostly myth, but there's a kernel of truth in there. Your metabolism can slow if you push the calorie deficit too far. You can eat 100 fewer calories, but how are you going to be sure that you're burning 400 more? And how are you going to stop your body from burning less (hint: you really can't).
I'm not saying that your plan won't work, just that it might not. You can't "force" the math to work out, because we really don't know a heck of a lot about how and why metabolism can slow down for some people, and yet doesn't seem to for others (or when we do know why, there's not a whole heck of a lot that can be done about it).
What I am saying is experiment with different calorie levels, different carb levels, and different amount of exercise, and just be happy with whatever weight loss results as you learn what your body works best on (and pay attention to how you feel, not just how much you lose. Losing faster isn't always better than losing slower).
I believe in the math of weight loss, but weight loss is more like algebra than "straight" addition, multiplication, subtraction, and division. The "calories expended" part of the equation is an unknown and is affected by all sorts of things, including activity level, exercise, sleep, environmental temperature, calories in, food choices, immune and healing needs... a whole bunch of stuff you have absolutely no control over whatsover.
For example, I lose about the same on 1500 calories of high carb foods, as I do on 1800 calories of moderately low-carb. I lose even better on 1800 or more of very low-carb, but faster loss comes with too high a price tag (feeling horrible). I choose the 1800 calories of moderately low-carb.
I can't tell for sure why my body burns better on lower-carb, but I do have a clue - my body temperature is almost a full degree higher on lower carb. On high-carb, my temperature is almost never over 98 degrees unless I'm very sick. It took years to convince doctors that for me 98 degrees was a fever, and 99 usually signalled pneumonia.
If you're going to experiment with carb levels, DON'T compare the first two weeks. You'll hold onto more water with high-carb, so if you compare the first two weeks of weight loss, you'll falsely conclude that low-carb is faster. Likewise, when you switch from low-carb to higher-carb, you'll see a gain (that isn't fat gain, it's just the extra water your body needs to process the extra carbs).
The water difference isn't that important so don't stress about it (following low-carb just because of the couple extra pounds of water you're not carrying around to digest the carbs, isn't the best strategy - especially if you're someone who feels better on higher carb. You need to want to have the energy to be able to exercise more than you want to be at the lowest weight just because you can manipulate it).
Because the "calories out" isn't under your direct control, and you never know what could help you maximize it, all you can do is experiment and compare the results.
It's possible that two pounds, or even one pound may not be feasible for you at your current weight.
That is hard to hear, because we've been taught to want and even demand rapid weight loss.
