Take the 2 SINs over to the RHS to leave the 2 x terms on the LHS and solve for x.
Post your solution if you think the answer is incorrect.

Take the sinx and consider it to be sin(½x + ½x)
You can the rewrite the equation as: sin(½x + ½x) + sin½x = 0
Apply the trig identity for Sin2A to the sin(½x + ½x) and you should be on your way to solving the equation

Glad to Help.
