Homogeneous Equations

Algebra Level 4

\((a+\alpha )x+\alpha y+\alpha z=0\\ \\ \alpha x+(\alpha +b)y+\alpha z=0\\ \\ \alpha x+\alpha y+(\alpha +c)z=0\)

Given that a,b,c are non-zero real numbers satisfying the system of equations above.

The given system of equations have a non-trivial solution if \({ \alpha }^{ -1 }=k({ a }^{ -1 }+{ b }^{ -1 }+{ c }^{ -1 })\) then what is the the value of 'k'?
