    I mean, what is the relation between the 26.4 and the w? I already know what the w stands for.

    Are they being added? Subtracted? Multiplied? Divided?

    So to get the w alone, divide 26.4 on both sides.

    \[\large \frac{26.4w}{26.4}~=~\frac{285.12}{26.4}\]

    It would look like this right? \[\large w~=~10.8\] So that means that w is 10.8 units
