Answer:

For this case we can propose an equation that will allow us to find the price of one of the books knowing the price of the other.

x: Let the variable that represents the price of the book with a green sticker

y: Let the variable that represents the price of the book with a yellow sticker

According to the statement we have:

x=(y)/(2) -2

y=2(x+2)

Finally, we can substitute the price of one of the books and clear the value of the other as the case may be.

x=(y)/(2) -2
