Answer:
16 Girls
Step-by-step explanation:
Let x be the number of boys.
Let y be the number of girls.
So we know that:
y = 2x
y + x = 24
We can get the answer through substitution. Since we know that y = 2x, we can insert that into our second equation by replacing the y with the equation we came up with for y in the first equation.
[tex]y + x = 24[/tex]
[tex]2x + x =24[/tex]
[tex]3x =24[/tex]
[tex]x =\frac{24}{3}[/tex]
[tex]x =8[/tex]
With that, we insert that answer into our first equation:
y =2x
y = 2(8)
y = 16
So there are 16 girls.
