The number (x) in: "1 more than twice a number is 451" 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 451.
To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 451
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 = 451
2x + 1 - 1 = 451 - 1
2x = 450
2x/2 = 450/2
x = 225
Answer = 225
The answer above is correct, because twice 225 is 450, and 1 more than 450 is in fact 451.
