+. +
[ ] _ [. ]. = 6
" "
13 8
Who can do dis?

Answer 1

Let the equations be =

A + B = 8

+   + =

C – D = 6

=   =

13 8

This gives;

A + B = 8

A+C = 13

B+D = 8

C – D = 6

 

Now Subtract eq (2), (3) and (4) from equation (1), the answer would be -2c=19

Therefore C=9.5

Substituting the value of C we get d=3.5

Similarly b=4.5 and a = 3.5
