Given  :

 ___       +       ___     =  8

    x                    -

____      x     _____   = 9

 =                       =

21                       5

To Find :  Values

Solution:

a       +     (8 - a)      =  8

x                -

b      x      (3 - a)        = 9

 =               =

21                 5

ab    = 21

b * (3 - a)  = 9

=> a/(3 -a)  = 21/9

=> a/(3 - a)  = 7/3

=> 3a = 21 - 7a

=> 10a = 21

=> a  = 21/10

   b  =  10  

8 - a  = 8 - 21/10  = 59/10

3 - a  =  3 - 21/10  = 9/10

21/10       +  59/10      =  8

x                  -

10        x        9/10         = 9

 =                 =

21                 5

2.1       +    5.9      =  8

x                  -

10        x      0.9         = 9

 =                 =

21                 5
