Question

_+_=8
+ +
_-_=6
= =
13 8

​

Answer 1

Answer:

let assume that the empty is a, b, c, d. then we get a+b=8 , c-d=6 , a+c=13, b+d=8 . then, by substracting a+b=8 and a+c=13 . we get -c-b=5 assume this as eq 1 . then similarly solve another one we get c-b=-2 assume this as eq 2 . then solve this two eq, we get 2b=3

b=3/2 . by substitute b value in above abcd form we get a, b, c, d value. by substituting this in the above question we get our required answer
