Answer:
Step-by-step explanation:
Given that the number of males in the classroom is three more than twice the number of females.
the total number of students is 57
Let x be the no of males then no of females = [tex]57-x[/tex]
Also we have 3 more than twice no of females as
[tex]2(57-x)+3[/tex]
This equals x
[tex]2(57-x)+3=x\\114-2x+3=x\\3x=117\\x=39[/tex]
No of males = 39, no of females = 18
