The number (x) in: "1 more than three times a number is 408" 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 1, you get 408.
To solve this, you first write the problem as an algebra equation as follows: 3x + 1 = 408
Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 1 = 408
3x + 1 - 1 = 408 - 1
3x = 407
3x/3 = 407/3
x = 135.67
Answer = 135.67
