Given an nxn grid, mark 2 points as the "start" and "finish"
Under what conditions is it possible construct a Labyrinth (a single route maze, no intersections) that occupies every square starting at the "start" point and stopping at "finish" ?

Left image is an example. Can you construct one for the right image?

Color every other square in a checkerboard pattern. In order to start at a white square and end at a black square, n must be even since the number of moves to go from a white square to a black square is always even.

so please go ahead and post something okay :)

the spirit of your argument is almost right. the S and E need not be on opposite colored squares. is it possible always construct a path if S and E are on same colored squares when n is odd? you imply in a kind of way that it's possible to construct any path on a square grid of even side length, but you didn't prove this.

A + B = 10
B = 10 - A
A + C = 20
C = 20 - A
B + C = 24
(10 - A) + (20 - A) = 24
30 - 2A = 24
30 - 24 = 2A
6 = 2A
3 = A
A + B + C
A + 10 - A + 20 - A = ?
-A + 30 = ?
-3 + 30 = ?
27 = ?

rather convoluted way of solving it
2(A+B+C) = 54
54 / 2 = 27

It isn't.
It's "solving" backwards from the solution you already know though

Your system has infinitely many solutions. OP's system has a single solution. They are not equivalent systems.

If you forgot about the other 3 equations? Sure. Otherwise just use them to get the A, B, C values easily if you care.
>>13545419 Is just a midwit solution where >>13545450 is a high iq shortcut.

Under what conditions is it solvable ? The S and E has to have one square in between them , or if you take the NxN matrix and subtract one square from the grid

Holy shit. I was joking with the "high iq" but you seem like a peak midwit. You don't need to have someone procure a valid solution or guess at random. You just play with the numbers and look for patterns. Adding all 3 equations gives you 2(A+B+C)=54 and its downhill from there. You know A+B+C=27 and A+B=10 so you got C etc.

Substitute

24 - B = C, 10 - B = A into A+C = 20 --> (10-B) + (24- B) = 20

B equals 7 , plug into the first equation ; A =3 , then the second ; C =13.

All into the last equation = 27

No need for name-calling. This is why you should show your work, otherwise >>13545450 reads as:
>Solve:
>A+B=10
>A+C=20
>B+C=24
>A+B+C=?
>...
>2(A+B+C) = 54
That's a leap.

okay I made that post you're referring to
all I did was notice that ABC were all mentioned twice so I could put them all together in the same equation based on that, then divided it be two
I did omit the rest of my working out and proof

agreed, whether you do the clever thing by adding all three equations or just crunch through the linear algebra, this is something you should be able to do before posting some brazen opinion about finitism or defining real numbers or some shit
