   1. The problem statement, all variables and given/known data
   
   I'm stuck on a question that results in this equality
   
   sin 2x = sin 2y
   
   how do I solve that for x or y?
   the only identity is the double angle one I can use I think but I don't know how that would help.
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution
