try letting X be the weight ( in pounds) of each book to set up your equation
Hello, user948123!
Here we go again . . .
The 7 books weigh \(\displaystyle \text{THIS}\) pounds.
If 8 pounds is added, the combined weight is 22 pounds.
. . So \(\displaystyle \text{THIS}\) must be 14 pounds.'
Assuming the books have the same weight,
. . one book weighs: .\(\displaystyle 14 \div 7 \:=\:2\text{ poinds.}\)
