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,
