The airplane has seats for 144 passengers. The seats are arranged in 48 rows,
with 3 seats in each row.
• There are 132 passengers on a certain flight.
• There are exactly 2 passengers in x rows.
• There are exactly 3 passengers in y rows.
Write a system of linear equations that can be used to model the situation. Use
your system to determine the number of rows with exactly 2 passengers and the
number of rows with exactly 3 passengers. Show your work.

Respuesta :

The equation computed shows that there are 12 rows that has exactly 2 passengers and 36 rows exactly 3 passengers.

The equation that can be used to solve the information will be:

x + y = 48

2x + 3y = 132

How to illustrate the equation?

From the information given, it was stated that the airplane has seats for 144 passengers. The seats are arranged in 48 rows, with 3 seats in each row.

The equation that can be used to solve the information will be:

x + y = 48

2x + 3y = 132

Solving the above simultaneously, we will get y = 36.

Then we'll put the value of y back into the equation.

x + y = 48

36 + x = 48

x = 48 - 36

x = 12

Therefore, there are 12 rows that has exactly 2 passengers and 36 rows exactly 3 passengers.
