Question

A+B=14 A+C=16 B+D=14 C-D=4

Answer 1

Answer:

A=64/3,B=-22/3,C=-16/3,D=88

Explanation:

A+B=14

Let us suppose take

A=14-B....(1)

A+C=16

C=16-A

C=16-(14-B)

=16-14+B

C =2+B.......(2)

C-D=4

D=C-4

D=(2+B)-4

=-8-4B

D=-8-4B.......(3)

B+D=14

B+(-8-4B)=14

B-8-4B=14

-3B-8=14

-3B=14+8

-3B=22

B=-22/3.......(4)

A=14-B. C=2+B D=-8-4B

A=14-(-22/3). C=2+(22/-3) D=-8-4(-22/3)

A=14+22/3. C =2-22/3. D=-12(-22/3)

A=64/3. B=-22/3. C= -16/3. D=264/3

D=88
