<h3>How to solve an equation?</h3>
The hardcover book is $8 each and paperbacks for $4 each.
The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.
Therefore,
h = 4p + 2
Hence,
8h + 4p = 160
Therefore, the right equation are as follows:
h = 4p + 2
8h + 4p = 160
Hence, Jean-Paul should have written the second equation as h = 4 p + 2.
