If `x=(a)/(b+c)=(b)/(c+a)=(c)/(a+b)` then value of x is ?

If (x-a)/(b+c)+(x-b)/(c+a)+(x-c)/(a+b)=3 then value of x is

If (x)/(b + c - a) = (y)/(c + a - b) = (z)/(a + b - c) , then value of x(b -c) + y(c -a) + z(a - b) is equal to

If log x/(b-c) =logy/(c-a) = logz/((a-b) then the value of xyz is

If (x+a)/(b+c)+(x+b)/(c+a)+(x+c)/(a+b)+3=0a>0,b>0,c>0 then the value of x is

If (x)/((b-c)(b+c-2a))=(y)/((c-a)(c+a-2b))=(z)/((a-b)(a+b-2c)) then the value of (x+y+z) is :

If |(a-b-c, 2a, 2a),(2b, b-a-c, 2b),(2c, 2c, c-a-b)|=(a+b+c)(x+a+b+c^2) then thhe value of x is equal to (A) -2(a+b+c) (B) a+b+c (C) -(a+b+c) (D) 2(a+b+c)
