Question

plz slve it guys .... plzzzz

Answer 1

(a + b - c)/(a + b) = (b + c - a)/(b + c) = (c + a - b)/(c + a)
=> 1 - c/(a + b) = 1 - a/(b + c) = 1 - b/(c + a)
=> -c/(a + b) = -a/(b + c) = -b/(c + a)
=> c/(a + b) = a/(b + c) = b/(c + a)
=> (c - (a + b))/(c + (a + b)) = (a - (b + c))/(a + (b + c)) = (b - (c + a))/(b + (c + a))
=>c - a + b = a - b + c = b - c + a
=>c - a + b - (a + b + c) = a - b + c - (a + b + c) = b - c + a - (a + b +c)
=>-2a = -2b = -2c
=> a = b = c
