Question

A+b =10 , c+d = 17 , a+d =9 . solve it

Answer 1

Answer:THE RIGHT QUESTION IS

A+b= 14, c-d=10, a+c=15, b+d=16...find the value of a,b,c,d?

Step-by-step explanation:

Answer:

The values are

a=1.5

b=12.5

c=13.5

d=3.5

Step-by-step explanation:

Given:

a+b=14.................(1)

c-d=10..................(2)

a+c=15.................(3)

b+d=16.................(4)

Adding (3) and (4), we get

a+b+c+d=31.........(5)

Using (1) in (5), we get

14+c+d=31

c+d=17................(6)

Adding (2) and (6), we get

c-d=10..................(2)

c+d=17................(6)

2c=27

c=13.5

(6) gives

d=17-13.5

d=3.5

(3) gives

a+13.5=15

a=15-13.5

a=1.5

(1) gives

1.5+b=14

b=14-1.5

b=12.5

Solution:

a=1.5

b=12.5

c=13.5

d=3.5
