9 more than twice a number is 839

The number (x) in: "9 more than twice a number is 839" 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 839.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 839

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 = 839

2x + 9 - 9 = 839 - 9
2x = 830

2x/2 = 830/2
x = 415

Answer = 415

The answer above is correct, because twice 415 is 830, and 9 more than 830 is in fact 839.
