Answer:
 The number of students that bring their lunches is 12         
Step-by-step explanation:
Let
x -----> the number of students that bring their lunches
y -----> the total number of students in a class

  -----> equation A
 -----> equation B
 -----> equation B
substitute the value of y in equation A and solve for x
 
 
 
 
therefore
The number of students that bring their lunches is 12
