The method to solve for W can be applied to other formulas like this. 
What you want to do is isolate the unknown you are looking for. And what ever you do to isolate the variable you have to do to the other side of the equation. 

If it were A = L + W then you would subtract L from L +W leaving you with just W. What you do to one side you have to do to the other, so you would also subtract L from A leaving you with A-L = W 

Since you are multiplying L and W then you divide both sides by L leaving you with A/L = W.
