First we can write 9 equations from this table (better not to do it during the test). You have 9 equations and 7 unknows so it's good.
1=x+4
-5=y+4
m=z+4
7=x+e
n=y+e
10=z+e
2=x+f
4=y+f
5=z+f

You look for
m+n=z+4+y+e

You directly have
x=-3
y=-9
7=x+e --> 7=-3+e --> e=10
n=y+e --> n=-9+10 -->n=1
10=z+e --> 10=z+10 --> z=0
m=z+4 --> m=4

So m+n=5

Good luck for your test tomorrow zag, trust you
