find values of A,B,C & D in this question.
​

Answer 1

HEY MATE YOUR ANSWER IS HERE.....

ACCORDING TO QUESTION...

A + B = 8 -------- Eq 1

A + C = 13 -------Eq 2

B + D = 8 --------Eq 3

C - D = 6 -------Eq 4

from Eq 2 and 3

A + B = B + D ( as both have ADDITION 8)

A = D ------- Eq 5

now in Eq 2 and 4 ( ADDING Equations)

A + C + C - D = 13 + 6

A + 2C - A = 19 ( FROM Eq 5 )

2C = 19

C = 19/2

C = 9.5 --------Eq 6

now

C - D = 6

9.5 - D = 6

D = 9.5 - 6

D = 3.5 ---------Eq 7

B + D = 8

B + 3.5 = 8

B = 8 - 3.5

B = 4.5 --------Eq 8

A + B = 8

A + 4.5 = 8

A = 8 - 4.5

A = 3.5 --------Eq 9

THANKS FOR YOUR QUESTION HOPE THIS HELPS...
