Calculating the Number of Pages Read

To calculate the number of pages the student read on Saturday and Sunday, we can use the information provided in the question and the fact that the student read the same number of pages each day.

Let's denote the total number of pages in the book as T and the number of pages the student read each day as R. After reading for a week, the student had 109 pages left to read.

The equation representing the situation is: T - 7R = 109

We also know that the student read the same number of pages each day, so we can express R as: R = X + Y

Where X is the number of pages read on Saturday and Y is the number of pages read on Sunday.

Solving for the Number of Pages Read on Saturday and Sunday

Substituting R in the first equation, we get: T - 7(X + Y) = 109

Given that the student read the same number of pages each day, we can solve for X and Y.

Let's proceed with the calculation.
