Reconstructing the Question....

a     +     b     =      8

×             |

c     ×      d     =      9

||              ||

21            5

Answers:-

a= 2.1

b = 5.9

c = 10

d = 0.9

Step-by-step explanation:

a + b = 8 ----- eq. 1

a*c = 21 ----- eq. 2

b - d = 5 ----- eq. 3

c*d = 9 ----- eq. 4

Solving,

b = 5+d (from eq. 3)

a+5+d = 8 (from eq. 1)

a+d = 3, a = 3 - d

(3 - d)*c = 21 (from eq. 2)

3c - cd = 21

3c = 21 + cd

3c = 21 + 9, c = 10

ac = 21, a = 2.1

b = 8 - 2.1 = 5.9

cd = 9, d = 9/10 = 0.9

I hope u got ur answers.....
