Given:
Refer to the attachment for a proper question.
To find:
The required answer.
Solution:
Refer to the attachment to understand clearly.
There are four boxes in which we have to find the addition of 8 and 13, subtraction of 6.
Let the numbers be A, B, C, D respectively and form equations.
1) A + B = 8
2) D + B = 8
3) C - D = 6
4) A + C = 13
From (1) and (2) we get A = D
From (3) we get C = 6 + D
substitute C value in (4)
A + C = 13
=> A + 6 + D = 13
From (1) we know that A= D
So, A + 6 + A = 13
=> 2A + 6 = 13
=> 2A = 13 - 6
=> 2A = 7
=> A = 7/2
=> A = 3.5
We got A = D = 3.5
substitute A value in (1)
A + B = 8
3.5 + B = 8
B = 8 - 3.5
B = 4.5
Substitute A value in (4)
A + C = 13
3.5 + C = 13
C = 13 - 3.5
C = 9.5
Hence, the values of A, B, C, and D are 3.5, 4.5, 9.5, and 3.5 respectively.
