1. The problem statement, all variables and given/known data

Hey guys, having a trig brain fart here, can you point me in the direction of simplifying:

$$\frac{6cos\vartheta}{2sin\vartheta-3cos\vartheta}$$

or is it as simplified as it gets? \

2. Relevant equations

Thought about using double angle formula

3. The attempt at a solution
Just a point in the right direction would be helpful, i.e. what identity to use if the expression can be simplified

You could try double angle formulas, but then you will probably end up with
$$\frac{6 \cos\theta}{2 \cos 2\theta - \sin\theta}$$
or something like that.

You could rewrite $\sin\theta = \tan\theta \cos\theta$ and get rid of the cosine.

Other than that, I don't think there is much simplification possible.
