write out the equation:
8y=3+7y (I'm assuming y is the amount of comic books)
8=3+7
8=10
Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.

Answer:
n = m-a
Step-by-step explanation:
The formula is : ...(1)
a is actual cost of an item
m is original price
n is amount of coupon
We need to solve the formula for the amount of coupen.
Subtracting m to the both sides of equation (1).
a-m = m-n-m
-n=a-m
or
n = m-a
So, the formula for the amount of coupon is n = m-a.
