Answer:
x = -4 or x = 2
Step-by-step explanation:
Get unknowns on one side and know on other side.
Divide both sides by -2
X= -7
Add sin(x) to both sides
tan(x)sin(x)=sin(x)
Divide sin(x) from both sides
tan(x)=1
now you just have to figure out where tan(x)=1. you can figure this out from there by looking at the unit circle.
There’s a calculator for that
