1. 2sin(x) = 1 - sin(x)
- How do you simplify this or whatever you call it to get x on one side??? I've tried to divide everything by 2 and also adding sin(x) on both sides, etc but I can't seem to get x by itself.

2. 5cos(x) = 1/cos(x)
- Same with this one, I can't seem to get x on one side. Would you multiply both sides by cos(x) first or divide 5 on both sides?? Or are those 2 ideas wrong??
Please help me simplify this!!!

Please can someone help me with this???!!!!!
Please help me and thank you in advance!!!! ^_^
