HiI have doubts in a problem the iitjee question paper 2007.I have attatched the question. When i tried adding both the equations and solving them,i could get 5 solutions ,i.e,0,π,5π/6,2π,π/6.But when i solved the equations seperately one after the other and took the common solutions, i got the answer attatched with the question (2 solutions).why is it wrong to add the 2 equations and solve them(the 1st method i used)?
