Question 1116657
----------------------------------------------------
guests brought a certain number of photographs to use based on how many pages they will be assembling. 
---------------------------------------------------
-
----------------------------------------------
Sharon plans to assemble three small pages and seven large pages and brought a total of 26 photographs to use. 
---------------------------------------------
-
--------------------
Whitney brought 16 photographs which is enough to assemble three small pages and two large pages 
--------------------






-----------------------------------------------
...assuming that the number of photographs on a page remains constant how many photographs fit on a small page and a large page?
----------------------------------------------


That changes the description.


What you really want to do is this:

Try making x and y,  ratio of photos to pages for small page (x) and for large page (y).  With this "assumption" and variables, form a system

{{{system(3x+7y=26,3x+2y=16)}}}


You can eliminate the 3x to first find y; and use this y value to find x.

-

{{{y=2}}}------photographs on a large page


{{{3x+2*2=16}}}
{{{3x=12}}}
{{{x=4}}}-------photographs on a small page



Those seem the reverse of what would be expected.  Fewer on large page than on small page.
