  1. Jan 8, 2015 #1
    1. The problem statement, all variables and given/known data
    How to solve for Q in dQ/dt=2-0.1Q?

    2. Relevant equations
    None.

    3. The attempt at a solution
    dQ/(2-0.1Q)=dt
    Now what?

    I got t+C after integrating the right side but I don't know how to integrate the left side, is it ln abs(2-0.1Q)?

    Close but not quite. Write out your u substitution for that integral.
