# Urgent Homework watch

1. I can't seem to understand how to solve a four mark question in my maths homework. I really need help cause I have to submit the homework soon... Anyone who knows?

3sin(2x)-4=5sin(2x)-3
2. you should get 2sin(2x)=-1
then u can solve and x should be two values

are you sure? I'm kind of scared because it's a four mark question and the topic in class is identities... so there is no need to use the double angle identity?
