The argument invalid. Draw out the table to get

V W V->W W V
T T T T T
T F F F T
F T T T F
F F T F F



The premises are columns 3 and 4. The conclusion is column 5.

Notice how row 3 has all true premises, but a false conclusion. So this shows us that this argument is invalid.

V W V->W W V
T T T T T
T F F F T
F T T T F
F F T F F
