Final answer:
To represent the number of pages read by each student, we can use the variables 'x' and 'y'. The equations x = 28 and y = 24 can represent the number of pages read by Literatura and Carly respectively.
Step-by-step explanation:
To represent the number of pages read by each student, we can define the variable: x for the number of pages Literatura has read and y for the number of pages Carly has read.
Then, we can write two equations using the given information:
Equation 1: x = 28 (since Literatura has read 28 pages)
Equation 2: y = 2 * 12 = 24 (since Carly has a reading speed of 2 pages per minute and has read 12 pages so far)
