solve it..​

Answer 1

Solution:-

Explanation:-

We can form four equations

A+B = 8

C-D = 6

A+C = 13

B+D = 8

Lets solve these four equations and find the variables A, B, C & D

if we add the four equations

A+B+C-D+A+C+B+D = 8 + 6 + 13 + 8

=> 2(A+B) + 2C = 35

=> 2C = 35 - 2*8 (by replacing A+B)

=> 2C = 35 - 16 = 19

=> C = 9.5

from 2nd Equation

=>C - D = 6

=>D = C - 6

=>D = 9.5 - 6

=>D = 3.5

from 3rd equation

=>A+C = 13

=>A = 13 - C

=>A = 13 - 9.5

=>A = 3.5

from 4th equation

=>B + D = 8

=>B = 8 - D

=>B = 8 - 3.5

=>B = 4.5

i hope it helps you.
