Question

dum hai to solve it buddies​

Answer 1

Heya!!!

A + B = 8 ... equation ( i )

C - D = 6 .... equation ( ii )

A + C = 13 ... equation ( iii )

B + D = 8 ..... equation ( iv )

Solve equation i and iv we get

A = D

Solve equation ii and iii we get

A + D = 7

2D = 7

D = 7/2 And A = 7/2

Now, put value of D in Equation ii we get

C = 19/2

put value of A in Equation i we get

B = 9/2

So, A = 7/2 , B = 9/2 , C = 19/2 And

D = 7/2
