Answer :
Answer:
Number of boys who attended the community service event = 10
Step-by-step explanation:
Let [tex]x[/tex] denotes number of girls and [tex]y[/tex] denotes number of boys.
Twenty-six students attended the community service event.
So,
[tex]x+y=26[/tex]
The number of girls was 4 fewer than twice the number of boys.
[tex]x=2y-4[/tex]
Put [tex]x=2y-4[/tex] in [tex]x+y=26[/tex]
[tex]2y-4+y=26\\3y=26+4\\3y=30\\y=10[/tex]
So,
Number of boys who attended the community service event = 10
