I'd like to be able to rearrange some formulas involving inequalities,
to get the inequality in terms of a certain variable.  How can this be
done in Mathematica 3.0?  For example, I'd like to get 't' in the
equation below on the left side by itself:

  lambda^2 t^2 < alpha - (c ( Abs[t] - r)^2)/2

What I thought would be obvious, 

  Solve[lambda^2 t^2 < alpha - (c ( Abs[t] - r)^2)/2, t]

doesn't work.  Nor does Eliminate seem suitable.  So what should one do?

Sorry to ask what is probably an ignorant question.
