there are 24 girls and 28 boys and 52 students in all
if there are 50 students there are 23 girls and 27 boys
the formula is
b - 4 = g
g + b = 52
52 - 4 = 48
48 / 2 = 24(number of girls)
24 + 4 = 28(number of boys)

if there are to be less than 52 students and 4 more boys than girls we need the highets number below 52 divisible by 4 , which is 48
so there are totally 48 students in the class
if the girls are x in number than boys are x +4 in number
so answer is got by equation-- x+x+4= 48
the number of girls is 24 and boys are 24= 4 = 28
and total students are 24+28= 52

Let x= the number of girls, then x+4= the number of boys
x+x+4=52, 2x=52-4,2x=48, x=24
You have 24 girls, and 28 boys in the class.

This isn't an inequality (unless you thing having more boys than girls in the class is an inequality :)). It is a system of 2 equations & 2 unknowns:
b=g+4
b+g=52
g+4+g=52
2g=48
g=24
b=24+4=28
check
24+28=52

Let
x = the number of girls
x + 4 = the number of boys
52 the total students
- - - - - - - - - - - - - - - - - - - - - - - - - - -
x + x + 4 = 52
2x + 4 = 52
2x + 4 - 4 = 52 - 4
2x = 48
2x/2 = 48/2
x = 24
The answer is x = 24
The solution set is { 24 }
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Check
x + x + 4 = 52
24 + 24 + 4 = 52
24 + 28 = 52
52 = 52
- - - - - - - - - - - - - - - - - - - - - - - - - -
There are 24 Girls In class
There are 28 Boys In class

i lll explain the whole system to yu
first lets assume ... let the boys be 'x' and girls be 'y'
so in the class total students will be 'x+y<52' as there are less than 52 students
now girls are 4 more than the boys so 'y+4=x'
now solve.
answer will be boys 28 and girls less than 24
simple enough ...

x+(x+4)<52 x is the number of girls x+4 is number of boys
2x+4 <52
2x <48
x<24 and you can't have a fraction of a person
27 or less boys and 23 or less girls because it says there are less than 52 total.

let x= no. of boys
let y = no. of girls
x+y<52
where x=y+4
y+4+y<52
2y<48
y<24
x=24+4
x<28
there are at most 27 boys and at most 23 girls
