Since the ratio of markers to pens was 5 : 7, the number of markers can be represented by 5x and the number of pens can be represented by 7x where x is some positive integer. We can create the equation for the number of markers:
5x = 35
x = 7
Originally, there were 35 markers and 7 x 7 = 49 pens. Since 6 pens were removed, 43 pens were left in the drawer.
