Jean-Paul's error is that he should have written the second equation as h = 4 p + 2.

<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.

Answer:
x = 50 in
Step-by-step explanation:
Since it is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
14^2 + 48^2 = x^2
196 + 2304 = x^2
2500 = x^2
Take the square root of each side
sqrt(2500) = sqrt(x^2)
50 =x
x = 50 in
