I don't need help with the physics, it is simply the algebra that I can't figure out in this problem. Here am where I am at:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] -m_{1} a + \mu ( m_{1} g \cos \theta ) + m_{1} g \sin \theta = \frac{\m_{2} a +m_{2} g \cos \theta }{ \cos \theta } [/tex]

I need to solve for a. How the heck do I do this? How can I factor the a's into just one a?
