Find the value of X,Y and Z in the following
X X X X
Y Y Y Y
Z Z Z Z
.
Y X X X Z

• (x+y+z)(1000+100+10+1)=10000y+(1000+100+10)x+z
  X-8889y+1110z=0
  Possible when x=9
  Y=1
  Z=8

• 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
