45 pages total 3 on last page 45-3=42 there are 42 on the rest of the pages on each page, there are 2 more pages in album than then stamps on pages
amount of stamps on pages with equal number of stamps is A=numberofpgest times number of stamps on pages number of pages=p number of stamps per papge=s a=ps
2 more pages than stamps on pages p=2+s total number of stamps per page is s=(45-3)/(p-1) (what I did is I first got rid of number of stamps on last page, then got rid of the last page) P=2+s s=(45-3)/(2+s-1) s=42/(s+1) times s+1 both sides s^2+s=42 minus 42 s^2+s-42=0 factor (s-6)(s+7)=0 set equal to zero s-6=0 s=6
