Answer 3

Calculating the Number of Athletes Selected from Each School

To solve this problem, we can use a system of equations. Let's denote the number of athletes selected from the first school as x and from the second school as y. We are given that the total number of athletes selected is 79, and the number of athletes selected from the first school is 11 more than the number selected from the second school.

We can express this information in the following equations: 1. x + y = 79 (total number of athletes selected) 2. x = y + 11 (number of athletes selected from the first school is 11 more than the number selected from the second school)

Solving the Equations

We can solve this system of equations to find the values of x and y.

Substituting the value of x from equation 2 into equation 1: y + 11 + y = 79 2y + 11 = 79 2y = 79 - 11 2y = 68 y = 34

Substituting the value of y back into equation 2: x = 34 + 11 x = 45

Answer

So, the number of athletes selected from each school is: - 45 athletes from the first school - 34 athletes from the second school
