Find the value of $A + B + C$ if :

$A = (7 x y + 5 y z - 3 z x)$
$B = (4 y z + 9 z x - 4 y)$
$C = (- 3 x z + 5 x - 2 x y)$

5 x y + 9 y z + 3 z x + 5 x - 4 y

Solve the following:
Add $7 x y + 5 y z - 3 z x, 4 y z + 9 z x - 4 y, - 3 x z + 5 x - 2 y$

$4 x y - 5 y z - 7 z$

$- 5 x y + 2 y z + z x$

$- 2 x y - 3 y z + 3 z x$

------------------------------

When $4 y z + 9 z x - 4 y$ and $- 3 x z + 5 x - 2 x y$ are added, we get $4 y z + 6 x z - 2 x y - 4 y + 5 x$ .
