    You will see that this is really easy. Just follow this method:

    1. Rearrange equation to have like terms on the same side:
    - All terms with the same variable go on the same side
    - Any terms with a unique variable goes with the constants

    So, we have:

    mw - t = 2w + 5

    Subtract 5 from both sides:

    mw - t - 5 = 2w + 5 - 5

    mw - t - 5 = 2w

    Subtract mw from both sides:

    mw - t - 5 - mw = 2w - mw

    t - 5 = 2w - mw

    2. Factor out a w on the right side of the equation:

    t - 5 = w(2 - m)

    Divide both sides by 2 - m:

    \frac{t - 5}{2 - m} = \frac{w(2 - m)}{2 - m}

    \frac{t - 5}{2 - m} = w

    And there you are.
