Are you sure that the equation isn't 3y-21%2Bxy-7x ??


3y-21%2Bxy-7x Start with the given expression


%283y-21%29%2B%28xy-7x%29 Group like terms


3%28y-7%29%2Bx%28y-7%29 Factor out the GCF 3 out of the first group. Factor out the GCF x out of the second group


%283%2Bx%29%28y-7%29 Since we have the common term y-7, we can combine like terms


So 3y-21%2Bxy-7x factors to %283%2Bx%29%28y-7%29
