Solve the equation with 0 ≤ α ≤ 2pi. Give exact answers if possible.

sin(2α) + 3 = 4

I need help isolating the sin so that it is by itself. How would I do that? I get stuck at this point:

sin(2α) + 3 = 4

sin(2α) = 1

What would I need to do next in order to isolate sin in order to solve this problem? Thank you.(Nod)
