Thank you I shoud have gotten that one was pretty easy
To create and solve the equation, let's follow these steps:
1. Assign a variable to represent the unknown number. Let's choose "x" as the variable.
2. Translate the given information into mathematical terms. The phrase "nine less than a number" can be written as "x - 9."
3. Set up an equation using the translated information. According to the problem, "nine less than a number is fifteen," which can be represented as: x - 9 = 15.
4. Solve the equation for the variable. Begin by isolating the variable on one side of the equation. To do this, add 9 to both sides of the equation:
x - 9 + 9 = 15 + 9
This simplifies to:
x = 24
5. Therefore, the unknown number is 24.
