Answers
Given : The number in each cell is the sum of numbers in cells in two neighbor cells
Two numbers are already written in the cells.
To Find : find value of x
Solution:
Suppose right side of 10 is a
a = 10 + ( number right to a)
=> ( number right to a) = a - 0
a - 10 = a + number right to (a - 10)
=> number right to (a - 10) = - 10
Similarly :
Then numbers will be like this
10 a (a - 10) - 10 - a 3
now - 10 + 3 = - a
=> - 7 = - a
=> a = 7
Complete filling :
10 7 -3 - 10 - 7 3
3 10
-7 7
-10 -3
-3 7 10 3 -7 -10
x = 7
