Let us come from Left side, the answer part (Y) is the carry. The max Carry that can be generated can be 1 or 2. Let us consider Y=1; so it will become
X X X X
1 1 1 1
Z Z Z Z
---------
and for the right side X+1+Z to become Z the only option for X=9 and the carry is forwarded. The next stage to satisfy the Z=8,

9 9 9 9
1 1 1 1
8 8 8 8
---------------
1 9 9 9 8
---------------
X=9,Y=1,Z=8
