Answer 2

Answer:

Step-by-step explanation:

a+b=8  --1

a+c=13 --2

b+d=8  --3

c-d=6 ---4

Subtract 1 from 2 --A

Add 3 and 4--B

Add A and B

Substitute value of c in A

Substitute in 1

a+b=8

a+4.5=8

a=3.5

c-d=6

9.5-d=6

d=3.5

Hence the value of a , b, c and d are 3.5 ,4.5 , 9.5 and 3.5 respectively.
