Step-by-step explanation:

The given expression is

$(xy-zy)/(y)\cdot(xw-xy)/(yz-yw)$

Then, we can multiply the fractions as

$\begin{gathered} ((xy-zy)(xw-xy))/(y(yz-yw))=(xy(xw)+xy(-xy)-zy(xw)-zy(-xy))/(y(yz)-y(yw)) \\ \\ =(x^2yw-x^2y^2-xyzw+xy^2z)/(y^2z-y^2w) \\ \\ =(y(x^^2w-x^2y-xzw+xyz))/(y(yz-yw)) \end{gathered}$

Finally, we can simplify the y to get

Answer:

So, the answer is
