Please help me with this equation!

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

At a scrapbooking party, guests brought a certain number of photographs to use, based on how many pages they will be assembling. Thi plans to assemble 7 small pages and 5 large pages and brought a total of 37 photographs to use. Katherine brought 19 photographs, which is enough to assemble 1 small page and 3 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?

Two variables equation. You can put small page as variable x and then the large page as y. E.g for the first equation : 7x + 5y = 37 etc. then solve the equations.

You will have a pair of simultanious equations. Which will be (using s for small and l for large) 7s+5l=37 and s+3l=19 we can solve this by either multiplying the second equation by 7 and subtracting one from the other, or we can use substitution by making s the subject of the second and subbing it into the first then solve for l. Your choice :) if you have any more queries get in touch.
