Merry Christmas! ^^
, knowing this we can multiply/ divide by x, y or z.
Starting from the first relation, we have:
We know that , so that, yz which is kind of a problem for us, can be written as :
For x=2: . That means that we write our equation this way:
So we know that: . x can then be 2, 4 or 6.
We can (and actually should) do the same thing for y and z, so y and z can also be 2, 4 or 6.
