1 more than twice a number is 399

The number (x) in: "1 more than twice a number is 399" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 1, you get 399.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 399

Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 1 = 399

2x + 1 - 1 = 399 - 1
2x = 398

2x/2 = 398/2
x = 199

Answer = 199

The answer above is correct, because twice 199 is 398, and 1 more than 398 is in fact 399.
