Step-by-step explanation:
We are given that an expression
We have to simplify the expression and find the coefficient of x and constant term.
Combine like terms then we get
It is compared with the equation of two variables
Where a= Coefficient of x
b=Coefficient of y
c= Constant term
Then, we get
a=2,b=7,c=12
Coefficient of x,a=2

Step-by-step answer:
If there are 40% students that are girls , and the rest are 250 boys. Then that must mean there are 60% boys. Because that is the compliment.
