A truck rental company charges a $25 rental fee when someone rents a
truck in addition to an hourly rental rate of $15 per hour. If a customer paid
$100 for a truck rental, how many hours did the customer use the truck?

So basically, this is an equation.

15x + 25 = 100

First, lets do the inverse operations tactic.

Subtract 25 from both sides, causing the 25 and -25 to cancel each other out. 100 becomes 75.

15x = 75.

Divide both sides by 15.

15/15 = 1, so it really just leaves the x by itself because the 1 has no value here.

75/15 = 5.

So, x = 5.
