Can anyone solve or help me find solutions for:

x + z - y = (0 or 15)

with x, y, and z ranging between 0 - 15?

Why not write C/C++ program?

#include <stdio.h>

int main( void )
{
	int counter = 1;
	for( int x = 0; x <= 15; x++ )
	{
		for( int y = 0; y <= 15; y++ )
		{
			for( int z = 0; z <= 15; z++ )
			{
				int result = x + z - y;
				if( ( result == 0 ) || ( result == 15 ) )
				{
					printf( "%d. X=%d Y=%d Z=%d\n", counter, x, y, z );
					counter++;
				}
			}
		}
	}
	return( 0 );
}

Thank you. Seemed relatively simple at first. I was able to find a number of solutions myself, but the inner positions where no coordinate is zero or 15 were giving me a headache.

272 integer results... do x, y, and z have to be integers? The original problem statement did not state that.

Yes, only needed the integers.

Somewhat embarrassed to say its for Minecraft. The normal order of events can alter at these particular coordinates. They repeat nigh infinitely across the world too, so should be extremely  useful.

I assume x, y, and z must be integers.

  First x+ z- y= 0.

If x= 0 then z-  y= 0 so z= y.

(0, 0, 0), (0, 1, 1), (0, 2, 2), ..., (0, 15, 15)

If x= 1 then z- y= -1 so z= y- 1

(1, 1, 0), (1, 2, 1), (1, 3, 2), ..., (1, 15, 14)

If x= 2 then z- y= 2 so z= y- 2

(2, 2, 0), (2, 3, 1), (2,  4, 2), ...., (2, 14, 12)

continue.
