Well, in xy-wy  = t,  you know that xy and wy both have y in them. (Yeah, that's not really a good explanation -_-)

So you can make that into: y(x-w) = t. Because if you distribute y to (x-w), the result is the same as the original. 

 

Now, we have y(x-w) = t.

We need to isolate y to solve for y.

 

So divided both sides by (x-w) to isolate y.

you get y = t/(x-w)

 

And that's the answer.

Correct me if I am wrong. laugh
