anonymous · Answer

2 + 1/3 z

jim766 · Answer

2 is right....

1/3 is right...   but the z started out on the top...and you didnt do anything with it, so
                         it should stay on the top

2 + z/3

anonymous · Answer

The book says the answer is 
K=1/3 (z+6)

jim766 · Answer

yeah , it means the same thing....     1/3(z + 6)     distribute
                                                        1/3(z) + 2
                                                        z/3 + 2
