The number (x) in: "9 more than three times a number is 453" 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 453.
To solve this, you first write the problem as an algebra equation as follows: 3x + 9 = 453
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 = 453
3x + 9 - 9 = 453 - 9
3x = 444
3x/3 = 444/3
x = 148
Answer = 148
