Answer 1

Answer:

a=c=7/2

b=9/2

d=19/2

Step-by-step explanation:

follow the above picture

we have 4 equations

a+b=8

b+c=8

d-c=6

a+d=13

now by solving first 2 we get

a=c

now by substituting it in equation we get answers as

a=c=7/2

b=9/2

d=19/2

7/2+9/2=8

9/2+7/2=8

19/2-7/2=6

7/2+19/2=13
