Z = 3                                              (This equation is a given)

z(y) = 12                                       ( This equation is also given) 

3y = 12                                         (as z = 3, plug 3 into z)

3y/3 = 12/3                                   (isolate the y by dividing 3 to both sides) 
                                                  * you divide 3 to both sides because of the equal                                                             sign. What you do to one side you do to the                                                                    other
y = 4                                             (answer for y)

y + 5                                             (what you are solving for)

(4) + 5 = 9                                    (As y = 4, plug in 4 for y in this equation)

y + 5 = 9                                       (4 + 5 =  9, or addition property)

9 is your answer           

hope this helps
