Step-by-step explanation:

A-B = 3

D= 2*A...........EQ 1

B = 2*C ...........EQ 2

D- C = 20 ..........EQ 3

from eq 1,2 and 3

2*A- B/2 = 30

4 A - B = 60 ........EQ 4

A- B = 3

A = 3+ B

put thw value in eq 4

4* ( 3+B ) - B = 60

12 + 4B -B = 60

12 + 3B = 60

3B = 48

B = 16

A= 6+3 = 19

D = 38

C = 8
