The number (x) in: "1 more than twice a number is 409" 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 409.
To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 409
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 = 409
2x + 1 - 1 = 409 - 1
2x = 408
2x/2 = 408/2
x = 204
Answer = 204
The answer above is correct, because twice 204 is 408, and 1 more than 408 is in fact 409.
