Answer:
x=8/3
y= -20/9
Step-by-step explanation:
4X + 3Y -4 =0
Linear egquations must in

so 4X + 3Y =4
THEN
3X + 9Y = - 12
next use calculator to solve it or you can use traditional way

Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25
