Answer 2

Solving for the Mass of Each Backpack

To solve for the mass of each backpack, we can set up a system of equations based on the given information.

Let's denote the mass of the first backpack as x kg and the mass of the second backpack as y kg. We are given that the total mass of both backpacks is 17 kg, and the mass of one backpack is 3 kg less than the other.

Setting Up the Equations

1. The total mass of both backpacks is 17 kg: - This can be represented as the equation: x + y = 17.

2. The mass of one backpack is 3 kg less than the other: - This can be represented as the equation: x = y + 3.

Solving the System of Equations

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

Substitute the value of x from the second equation into the first equation: y + 3 + y = 17.

Simplify the equation: 2y + 3 = 17.

Subtract 3 from both sides: 2y = 14.

Divide by 2: y = 7.

Now that we have the value of y, we can find the value of x using the second equation: x = 7 + 3, x = 10.

Answer

So, the mass of the first backpack is 10 kg and the mass of the second backpack is 7 kg.
