Now,

There will be four equation formed.

a+b=8. (1)

c-d=6. (2)

a+c=13. (3)

b+d=8. (4)

Solving equation (2) and (4)

c-d=6

b+d=8

_______

b+c=14 (5)

solving equation (5) and (3)

b+c=14

a+c=13

-_____

b-a=1. (6)

Now , solving equation (6) and (1)

b-a=1

a+b=8

_____

2b=9

b=$\frac{9}{2}$

Hence,rest of answer is c=$\frac{19}{2}$

d=$\frac{9}{2}$,

a=$\frac{7}{2}$

There are several solution for this question but I use mathematical method.
