9 more than twice a number is 817

The number (x) in: "9 more than twice a number is 817" 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 817.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 817

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 = 817

2x + 9 - 9 = 817 - 9
2x = 808

2x/2 = 808/2
x = 404

Answer = 404

The answer above is correct, because twice 404 is 808, and 9 more than 808 is in fact 817.
