If you get the missing numbers, share it with your friends on WhatsApp, Facebook and other social networking sites.
Let’s call the missing numbers as A, B, C & D.
Let’s write out the equations as follows;
- A + B = 8;
- C – D = 6
- A + C = 13 &
- B + D = 8
A + B = 8 = B + D
we can say;
A = D.
Substituting the value of A + D in (3) we get;
5. C + D = 13
Adding this with equation (2) we get.
C + D = 13
C – D = 6
2C = 19
C = 9.5
So substituting the value of C in (5) we get;
9.5 + D = 13
D = 3.5
Since A = D we have;
A = 3.5.
Putting value of A in (1) we get;
3.5 + B = 8
B = 4.5
So the missing numbers are as shown in the picture below;
