Given two real numbers p and q such that 1/p + 1/q = 1 and pq = 9, what is p + q?  

 

                                                   1/p + 1/q  =  1  

 

multiply both sides by pq                  q + p  =  pq  

 

but the problem says pq = 9  

 

therefore                                            q + p  =  9
