9 more than twice a number is 824

The number (x) in: "9 more than twice a number is 824" 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 824.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 824

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 = 824

2x + 9 - 9 = 824 - 9
2x = 815

2x/2 = 815/2
x = 407.5

Answer = 407.5

The answer above is correct, because twice 407.5 is 815, and 9 more than 815 is in fact 824.
