Answer 1

Answer:

PLEASE MARK ME AS BRAINLIEST...

Step-by-step explanation:

from (i),

a=8-b....(v)

putting (v) in (iii),

=>a+c=13

=>8-b+c= 13

=>c-b=5....(vi)

(ii)-(vi)=>

c-d=6

c-b=5

b-d=1....(vii)

now,

(iv)+(vii)=>

b+d=8

b-d= 1

2b = 9

=>b=4.5

putting b=4.5 in (vii), we get,

b-d= 1

=>4.5-d = 1

=> d= 4.5-1

=> d= 3.5

now,

putting d=3.5 in (ii) we get,

c-d=6

=>c-3.5= 6

=>c= 6+3.5

=>c= 9.5

putting c=9.5 in (iii), we get,

a+c=13

=>a+9.5= 13

=>a=13-9.5

=>a=3.5

so, the required numbers are:

3.5

4.5

9.5

3.5
