Let B and G represent number of boys and girls respectively,
B+G = 35
B = G+9
G + G+9 = 35
2G = 26
G = 13
B = 13+9 = 22
There are 13 girls and 22 boys.
B+G = 35
B = G+9
G + G+9 = 35
2G = 26
G = 13
B = 13+9 = 22
There are 13 girls and 22 boys.

Let x = number of girls in the class and x + 9 = number of boys in the class
x + x + 9 = 35 <--This is b/c you have a total of 35 students
Solve for x to get the number of girls
2x + 9 = 35
2x = 26
x = 13
So, there are 13 girls in the class
x + x + 9 = 35 <--This is b/c you have a total of 35 students
Solve for x to get the number of girls
2x + 9 = 35
2x = 26
x = 13

g + b = 35
b = g+9
g + (g+9) = 35
g = 13
b = g+9 = 22
b = g+9
g + (g+9) = 35
g = 13
b = g+9 = 22

35 divided by 2 is 17 (and a half)... plus 9 is 26 boys...
therefore, there are 26 boys and (35-26) 9 girls in the class...
therefore, there are 26 boys and (35-26) 9 girls in the class...

Let x equal the number of girls. If there are 9 more boys than girls, then we can agree that (x+9) equals the number of boys. Now...we know that the number of boys (x+9) and the number of girls (x) will add up to the total of number of students which equals 35. So to make an equation, you would say: boys (x+9) + girls (x) = 35
Now remove the words "boys" and "girls" and you are left with this equation: x+9 + x = 35 . Next, you can add the x to the other x and get 2x. So now your equation is this: 2x + 9 = 35 . Next you will subtract 9 from both sides of the equation and end up like this: 2x = 35-9 which equals 2x = 26. Divide 26 by 2 and x = 13. But remember, x is number of girls, and that's 13. Boys are x+9, That's 13+ 9 which equals 22.

Let y be the number of girls in the class
y + y + 9 = 35
2y + 9 = 35
2y + 9 - 9 = 35 - 9
2y = 26
2y/2 = 26/2
y = 13
There are 13 girls in the class.
y + y + 9 = 35
2y + 9 = 35
2y + 9 - 9 = 35 - 9
2y = 26
2y/2 = 26/2
y = 13
There are 13 girls in the class.

let g be girls. let b be boys. total number of students = 35
b + g = 35--(1)
b = g + 9----(2)
from (2), put b in (1)
g + 9 + g = 35
2 g = 35 - 9 = 26
g = 26 / 2 = 13
put g = 13 in (1)
b + 13 = 35
b = 35 - 13 = 22
boys = 22
girls = 13
verify:
b = 22 = g + 9 = 13 + 9 =22 = right hand side
b + g = 35--(1)
b = g + 9----(2)
from (2), put b in (1)
g + 9 + g = 35
2 g = 35 - 9 = 26
g = 26 / 2 = 13
put g = 13 in (1)
b + 13 = 35
b = 35 - 13 = 22
boys = 22
girls = 13
verify:
b = 22 = g + 9 = 13 + 9 =22 = right hand side

B+B+9=35
2b+9=35
2n=26
B=13 girls
That means there are 22 boys
2b+9=35
2n=26
B=13 girls
That means there are 22 boys

A class has 35 students,
there are 9 more boys than girls.
how many girls are there?
g + 9 = b
b - g = 9
b + g = 35
b = 22, g = 13
There are 13 girls.

Amount of boys = (Sum + difference)/2
Amount of girls = (Sum - difference)/2
boys: (35 + 9)/2 = 22 boys
girls: (35 - 9)/2 = 13
There are 13 girls and 22 boys.

35 - 9 ÷ 2 = 13. Fourth grade math.

35 divided by 2 is 17 (and a half). Plus 9 is 26 boys.
Therefore, there are 26 boys and (35-26) 9 girls in the class.
