Find the valueof?






Answer :

Let



So,
From forth row we get

y  + y + y + y = 20

4y  = 20

y  = 5

And

From second row , we get

y + x + x  + x  = 14 

y  + 3x    = 14    , Substitute y  = 5  we get

5 + 3x  = 14

3x  = 9

x  = 3

And

From first row we get

x + z + z  + y = 16   , Substitute value of x  and y we get

3 + 2z  + 5 = 16

2z  = 8

z  = 4

So,
