You and a friend are both reading a book. You read 2 pages each minute and have already read 55 pages. Your friend reads 3 pages each minute and has already
read 35 pages. Graph and solve a system of equations to find when the two of you
will have read the same number of pages. Since the number of pages you have
read depends on how long you have been reading, let x represent the number of
minutes it takes to read y pages.
