The given reactions are

$X^-2 + Y -> X +Y^-2........................(1)$

and

$X+Z^-2 -> X^-2 +Z..........................(2)$

Eq(1) reveals that Y is stronger oxidizing agent than X, because Y takes up 2electrons from $X^-2$ forming $Y^-2$

Eq(2) reveals that X is stronger oxidizing agent than Z ,because X takes up 2electrons from $Z^-2$ forming $X^-2$

So order of their of their oxidizing capacity is $Y>X>Z$

This implies that Y can oxidize both X and Z but X oxidizes Z

If we add this two equations (1) and (2) we get

$Z^-2+Y->Y^-2+Z...............................(3)$

Eq(3) reveals that Y is stronger oxidant than Z

Hence weakest oxidizing agent is Z
