HEY THERE!!!

=======================

THERE ARE 50 STUDENTS IN A CLASS,
AND THERE ARE 22 GIRLS.

SO TO FIND THE NUMBER OF BOYS,  THE EQUATION SHOULD BE,

LET x BE THE NUMBER OF BOYS,

x + 22 =50
x = 28

SO THE NUMBER OF BOYS IN THE CLASS ARE 28.

HENCE WE CAN FIND THE NUMBER OF BOYS BY USING THIS EQUATION.

Answer 2

Hey there !

Total number of students=50

Number of girls=22

Let the boys be x

We know that

Girls + Boys = Total

22+x=50 is the equation to find number of boys .

x=50-22=28
