Well, to get X+Y+Z = Z, we should have  X and Y as O which is not possible, So if we take X and Y such that X + Y = 10, we can get X + Y + Z = Z, carry 1.

At the next stage, we should get (carry)1+X+Y+Z = X, so we have to choose Y and Z such that Y + Z = 9. So, 1+X+Y+Z = X, carry 1.

At the next stage also, 1+X+Y+Z = X, carry 1.

At the final stage we have to get, 1+X+Y+Z = YX. Since, 1+X+Y+Z gives the value X and carry 1 we get the value fo Y as 1.

So, from Y+Z=9, we get Z=8 by substituting Y=1. and from X+Y=10, we get X=9.

So, X=9, Y=1, Z=8.
