Calculation of Gift Box Weights

To calculate the total weight of the gifts, we can start by finding the weight of each gift in both boxes and then summing them up.

Let's denote: - x as the weight of one gift in the first box - y as the weight of one gift in the second box

Given: - There are 78 gifts in the first box - There are 84 gifts in the second box - The weight of the second box is 3 kg more than the first box

We can set up the following equations:

1. The total weight of gifts in the first box is 78x. 2. The total weight of gifts in the second box is 84y. 3. The weight of the second box is 3 kg more than the first box, so we have the equation y = x + 3.

Solving for Gift Weights

To find the weights of the gifts, we can use the given information to solve for x and y
