Mathematics Differential equations help please!?

I am doing differential equations on a test, I can do alot of them and know the process. But one question frustrated me and I can't seem to sort out the algebra.

Q2c) Solve the following via "seperation of variables" technique.

(11-2x)dx/dt = (x+3)(x+1)

How do I go about placing all the x variables on the LHS of the equation so I can then integrate?

Please help, if anyone can describe the working out decently, I will be more than obliged to reward with best answer 10 pts.

    (11-2x)/((x+3)(x+1)) dx = dt. Take a integration!!!

    Divide (x+3)(x+1) over to the lhs and then multiply by dt to get (11-2x)dx/((x+3)(x+1))=dt.
