9 more than twice a number is 999

The number (x) in: "9 more than twice a number is 999" 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 999.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 999

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 = 999

2x + 9 - 9 = 999 - 9
2x = 990

2x/2 = 990/2
x = 495

Answer = 495

The answer above is correct, because twice 495 is 990, and 9 more than 990 is in fact 999.
