    values of k

    If K=\frac{a}{b+c}=\frac{b}{a+c}=\frac{c}{b+a}

    Find the possible values of K.

    In my view there is only one possible value of k i.e \frac{1}{2} when a=b=c but I am not sure about the answer!

    \frac{a}{b+c}=\frac{b}{a+c} leads to a(a+c) = b(b+c) or (a-b)(a+b+c) = 0

    You can have a=b or a+b+c=0

    I let you go on
