The system would be:

x + y = 27

y = 2x

How to write the system?

Let's define the variables x = number of boys and y = number of girls.

The first equation states that the total number of boys and girls is 27.

x + y= 27

The second equation states that the number of girls is twice the number of boys.

y = 2x

Then the system that represents this situation is:

x + y = 27

y = 2x
