Jose has a comic book collection that he keeps among five shelves with an equal number on each shelf his father add 20 comic books to the bottom shelf so now the shelf has 125 books how many total books are in his collection

Let's call the number of comic books on each shelf x.

Thus, the total number of comic books on the bottom shelf is x + 20.
Since the number of comic books on each shelf is the same, the total number of comic books on the shelves can be calculated as 5 * x.
So, the equation representing the total number of comic books on the shelves is 5x = (x + 20) + 125.
Simplifying the equation, we get 5x = x + 145.
Subtracting x from both sides of the equation, we have 4x = 145.
Finally, dividing both sides of the equation by 4, we find that x = 36.75.
Given that the number of comic books in the shelf should be a whole number, it is not possible for x to be 36.75.
Thus, there is no solution to the problem, and the total number of comic books in Jose's collection is undefined.
