9 more than twice a number is 814

The number (x) in: "9 more than twice a number is 814" 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 814.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 814

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 = 814

2x + 9 - 9 = 814 - 9
2x = 805

2x/2 = 805/2
x = 402.5

Answer = 402.5

The answer above is correct, because twice 402.5 is 805, and 9 more than 805 is in fact 814.
