Answer:

Number of boys who attended the community service event = 10

Step-by-step explanation:

Let x denotes number of girls and y denotes number of boys.

Twenty-six students attended the community service event.

So,

x+y=26

The number of girls was 4 fewer than twice the number of boys.

x=2y-4

Put x=2y-4 in x+y=26

2y-4+y=26\\3y=26+4\\3y=30\\y=10

So,

Number of boys who attended the community service event = 10
