Trigonometric equations question
Hi, I'm very confused with solving the following trigonometric equation:

Solve for $x$ for 0 (less than or equal to) $x$ (less than or equal to) $2 \pi$

$sin x tan x + tan x - 2sinx + cos x =0$

Im very confused, and would greatly appreciate any help.

Thanks,:)

Start by reducing this problem into terms of only $\sin x$ and $\cos x$ by using $\tan x = \frac{\sin x }{\cos x}$

After this look for a common denominator i.e in this case $\cos x$

I tried that, but am still having problems. I'm very confused, and am not sure on how to proceed.
