Question

if a+b-c/a+b=b+c-a/b+c=c+a-b/c+a and a+b+c=o then

Answer 1

a+b+c=0
then, -a=b+c and -b=a+c and -c=a+b therefore
L.H.S
(a+b-c)/a+b
(a+b+a+b)/a+b
2(a+b)/(a+b)
2
same in M.H.S. AND R.H.S.

Answer 2

Answer: here is your answer

Step-by-step explanation:

a+b+c=0

then, -a=b+c and -b=a+c and -c=a+b therefore

L.H.S

(a+b-c)/a+b

(a+b+a+b)/a+b

2(a+b)/(a+b)

2

same in M.H.S. AND R.H.S.
