The number (x) in: "9 more than three times a number is 459" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by three (same as three times) and then add 9, you get 459.
To solve this, you first write the problem as an algebra equation as follows: 3x + 9 = 459
Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 9 = 459
3x + 9 - 9 = 459 - 9
3x = 450
3x/3 = 450/3
x = 150
Answer = 150
