Answer:
x=65/n where x is 1 book and n the number of books
Step-by-step explanation:
If n is the number of books, lets say 1 book is "x", then
nx=65
x=65/n
for example
n=1 then x=65
n=2 then x=65/2
n=3 then x=65/3
7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
