The number (x) in: "6 more than three times a number is 405" 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 6, you get 405.
To solve this, you first write the problem as an algebra equation as follows: 3x + 6 = 405
Then you solve the equation by subtracting 6 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 6 = 405
3x + 6 - 6 = 405 - 6
3x = 399
3x/3 = 399/3
x = 133
Answer = 133
