As stated in the documentation, Solve deals primarily with linear and
polynomial equations.  For some specific values of k:

Off[Solve::"ifun"];

TableForm[Table[{k, FullSimplify[x /. 
          Solve[Tan[k*x]+m*Tan[x]==0, x]]}, 
    {k,0,2,1/2}], TableAlignments->{Left,Top}]

or assign values for both k and m and use numerical techniques.

<< ive been trying to solve an equation of the form

tan(kx) + m tan(x) = 0 , solving for x

but mathematica says " The equations appear to involve the variables to
be solved for in an essentially non-algebraic way. "

So is there another way to use mathematica to solve, or is it powerless
for this problem?
