1 more than twice a number is 400

The number (x) in: "1 more than twice a number is 400" 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 400.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 400

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 = 400

2x + 1 - 1 = 400 - 1
2x = 399

2x/2 = 399/2
x = 199.5

Answer = 199.5

The answer above is correct, because twice 199.5 is 399, and 1 more than 399 is in fact 400.
