9 more than twice a number is 909

The number (x) in: "9 more than twice a number is 909" 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 909.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 909

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 = 909

2x + 9 - 9 = 909 - 9
2x = 900

2x/2 = 900/2
x = 450

Answer = 450

The answer above is correct, because twice 450 is 900, and 9 more than 900 is in fact 909.
