9 more than twice a number is 455

The number (x) in: "9 more than twice a number is 455" 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 9, you get 455.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 455

Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 9 = 455

2x + 9 - 9 = 455 - 9
2x = 446

2x/2 = 446/2
x = 223

Answer = 223

The answer above is correct, because twice 223 is 446, and 9 more than 446 is in fact 455.
