$4 \sin (x) + 1 = 2 \sin (x)$

Step 1

Subtract $2 \sin (x)$ from both sides of the equation.

$4 \sin (x) + 1 - 2 \sin (x) = 0$

Step 2

Subtract $2 \sin (x)$ from $4 \sin (x)$ .

$1 + 2 \sin (x) = 0$

Step 3

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
