It's C.

From the table, we know:
m+n= (4+z) + (y+e) = 4+z+y+e
y+4=-5
z+e=10

But m+n= 4+z+y+e = (y+4)+(z+e) = -5+10 = 5

Its C - 5.

X = -3, y = -9, e = 10, f = 5, n = 1, z=0, m = 4

m+n = 5

Here it is.

From the question we could make the following equn.
4 + x = 1;4 + y = -5;4 +z = m
e + x = 7;e+y=n;e+z=10
f+x=2,f+y=-4;f+z=5

Now solving these equations you could get the values for the variables, and adding m+5 would give the result.
