Considering your current diagram ,

it should be ,

x + 1 +y +1 +z = 45
x +y +z = 43

y +1 +z = 20
y+z = 19---------(2)

x +1 +y = 30
x+y = 29--------------(3)
Adding (2) and (3) , we get , x +2y + z = 48


Solving we get, x + 2*y  + z - (x +y +z ) = 48 -43 = 5

Am I right in my approach ? KarishmaB MartyMurray
 

Yes, that approach is spot on.
