9 more than twice a number is 825

The number (x) in: "9 more than twice a number is 825" 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 825.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 825

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 = 825

2x + 9 - 9 = 825 - 9
2x = 816

2x/2 = 816/2
x = 408

Answer = 408

The answer above is correct, because twice 408 is 816, and 9 more than 816 is in fact 825.
