Question

Please give correct answer .​

Answer 1

Step-by-step explanation:

Solution :-

A+B = 8 ---------(1)

A+C = 13 --------(2)

B+D = 8 ----------(3)

C-D = 6 ------------(4)

On subtracting (1) from (2)

A+C = 13

A+B = 8

(-)

_______

C-B = 5

_______

-B+C = 5 ---------(5)

On adding (3)&(4)

B+D = 8

C-D = 6

(+)

_______

B+C = 14 --------(6)

_______

On adding (5)&(6)

-B + C = 5

B+ C = 14

(+)

________

0+2C = 19

________

=> 2C = 19

=> C = 19/2

=> C = 9.5

On Substituting the value of C in (6)

B+9.5 = 14

=> B = 14-9.5

=> B = 4.5

On Substituting the value of B in (1)

=> A + 4.5 = 8

=> A = 8-4.5

=> A = 3.5

from (3)

B+D = 8

=> 4.5+D = 8

=> D = 8-4.5

=> D = 3.5

Therefore,

A = 3.5 , B = 4.5 , C = 9.5 and D = 3.5

Answer :-

The values of A = 3.5 , B = 4.5 , C = 9.5 and

D = 3.5

Answer 2

Answer:

3.5+4.5

+ -
