Question 748450: What are the x's of: sin(x)+sin(-x)=2

Look at the unit circle to see how sine of x and sine of negative x are related. If you rotate a ray of 1 unit in the clockwise direction from the positive horizontal axis, then you have a -x. The sine of -x is the opposite of sine of positive x.
Your equation means,
FALSE.
