The formula for Degree of Unsaturation of an organic compound is given by

$\boxed{\large{U.D=C+1-\dfrac{H-N}{2}}}$

Here

$C=\text{No. of tetravalent atoms in compound}$

$H=\text{No. of monovalent atoms in compound}$

$N=\text{No. of trivalent atoms in compound}$

So by putting values in this equation,... we get

$\boxed{x=1,y=2,z=3}$

$\implies \boxed{x+y+z=6}$

How do you calculate it in the second case where there is a divalent atom present in the compound?

Divalent is not taken into consideration for U.D formula
