You need to get all x terms on one side so the other side =0, and then factorise to solve, setting each factor which can =0 to 0. If this is confusing, tell me.
Dividing results in loss of solutions. Always factorise.
What have you tried, OP?
I made up the question because I wanted to see whether i should divide or factorise in that situation. Thanks for your reply! By the way If you had: 2sinx/cost = -1/cosx and you cross multiplied, what would you do then?

Assuming that's cosx and not cost, I'd rearrange that to make it equal to 0 and see that it doesn't matter what cosx is as it is on the denominator.
