Ответ:
y/b books
Step-by-step explanation:
We know that there is a total of y textbooks. These y textbooks came in b boxes, with equal numbers of books in each of these b boxes.
To find how many books are in each box, take the total number of books and divide it by the number of boxes:
y ÷ b = y/b
Thus, there are y/b books in each box.
Hope this helps!

12 + x = 16 + 0.80x
12 = 16 -0.2x
-4 = -0.2x
x = -4/-0.2 = 20
