Answer 1

$\huge\underline{\red{\bold{Answer}}}$

✨ a+b= 8..........(1)
✨ a+c= 13.............(2)
✨ c-d= 6....................(3)
✨ b+d= 8......................(4)

subtracting equation (1) from (2)

we get ,

a+c-(a+b)= 13-8

c-b= 5
or c= 5+b

Now put this value of c in equation (3)

Now we get,

5+b-d= 6
b-d= 6-5=1
b-d=1.......................(5)

Now on adding both equations (5) and (4)
we get,

= equation (5)+(4)
(b-d) + (b+d)= 1+8
b-d+b+d= 9
2b= 9
Thus b= 9/2

Now put this value of b in equation (1)
a+b= 8
a= 8-b
a= 8-9/2
a= 7/2

putting this value of a in equation (2)
we get,
a+c= 13......from (2)
c= 13-a
c= 13-7/2= 19/2

Now put this value of c in equation (3)
c-d= 6.....from (3)
c-6= d
d= 19/2-6
d= 7/2

Hope this helps you.....^_^✌
