1 more than twice a number is 405

The number (x) in: "1 more than twice 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 two (same as twice) and then add 1, you get 405.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 405

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 = 405

2x + 1 - 1 = 405 - 1
2x = 404

2x/2 = 404/2
x = 202

Answer = 202

The answer above is correct, because twice 202 is 404, and 1 more than 404 is in fact 405.
