- v-5+w=v+31+49
w=85
w+y+13=y+x+31
x=67
w+x+49=31+x+y
y=103
31+x+y=-5+x+z
z=139
y+z=242 - 11 years agoHelpfull: Yes(80) No(0)
- v-5+w=v+31+49
w=75
75+x+49=31+x+y
y=93
then find z similarly so z=119.
y+z=93+119=212 - 11 years agoHelpfull: Yes(5) No(14)
- v+31+49=v+w-5
w=85
-5+x+z=62+z
x=67
201=98+y
y=103
z=139 - 11 years agoHelpfull: Yes(5) No(1)
- v+31+49=v+x+13 => x=67
31+67+y=w+y+13 => w=85
85+67+49=85+13+y => y=103
31+67+103=49+z+13 =>z=139
y=103
z=139
y+z=103+139=242. - 11 years agoHelpfull: Yes(2) No(0)
- since some of each row ,column and diagonal are equal
v+31+49=v+x+13 hence x=80-13=67
and v+31+49=v+(-5)+w hence w=80+5=85
and 31+x+y=49+x+w hence y=49+w-31=49+85-31=103
hence value of x+y=67+103=170 - 11 years agoHelpfull: Yes(1) No(5)

- sry there is a small mistake which i did.......
v-5+w= v+31+49 i.e w=85, 85+y+13=y+x+31 i.e x= 67
(31+67+y+49+z+13)= (85+67+49)*2
after solving this question we get,y+z= 242 - 11 years agoHelpfull: Yes(1) No(0)
- v-5+w= v+31+49 i.e w=85, 85+y+13=y+x+31 i.e x= 67
(31+67+y+49+z+13)= (85+67+49)
y+z= 41 - 11 years agoHelpfull: Yes(0) No(0)
