m=z+4
n=y+e

x+4=1 -> x=-3
y+4 = -5-> y =-9


x+e = 7 ->e = 10

z+e=10-> z=0

m = z+4 = 0+4 = 4
n = y+e = -9+10 = 1

m+n = 5

4+x = 1
4+y = -5
4+z = m
In the same way you will get
e+y = n
e+z = 10

from 4+y = -5 and e+y = n
e-4 = n+5
from 4+z = m and e+z = 10
e-4 = 10-m
equate last 2
10-m = n=5 ==>m+n = 5
