Calculating Wallpaper Usage for Two Rooms

To calculate the amount of wallpaper used for each room, we can use the information provided.

Let's denote: - x as the number of rolls of wallpaper used for the first room. - y as the number of rolls of wallpaper used for the second room.

From the given information, we have the following equations: 1. x + y = 9 (total rolls used for both rooms) 2. 4x + 5y = 108 (total wallpaper used for both rooms)

To solve for x and y, we can use the substitution method or any other preferred method.

Solving the Equations

Using the substitution method: 1. From the first equation, we can express x as x = 9 - y. 2. Substitute x in the second equation: 4(9 - y) + 5y = 108. 3. Simplify the equation and solve for y.

Calculating Wallpaper Usage for Each Room

After solving for y, we can then calculate the amount of wallpaper used for each room: - x = 9 - y - y = (calculated value) - Total wallpaper used for the first room = 4x - Total wallpaper used for the second room = 5y

Let's proceed with the calculations.
