Answer 1

Task a)

To solve this problem, we need to find the total number of gifts prepared by the students of both classes.

Let's assume that the number of gifts prepared by Class 2A is x.

According to the problem, Class 2B prepared 4 more gifts than Class 2A. So the number of gifts prepared by Class 2B is x + 4.

The total number of gifts prepared by both classes is the sum of the gifts prepared by Class 2A and Class 2B.

Therefore, the equation is:

x + (x + 4) = 26

Simplifying the equation:

2x + 4 = 26

Subtracting 4 from both sides:

2x = 22

Dividing both sides by 2:

x = 11

So, Class 2A prepared 11 gifts, and Class 2B prepared 4 more gifts, which is 11 + 4 = 15 gifts.

Therefore, the total number of gifts prepared by the students of both classes is 11 + 15 = 26 + 15 = 41 gifts.
