9 more than twice a number is 838

The number (x) in: "9 more than twice a number is 838" 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 838.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 838

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 = 838

2x + 9 - 9 = 838 - 9
2x = 829

2x/2 = 829/2
x = 414.5

Answer = 414.5

The answer above is correct, because twice 414.5 is 829, and 9 more than 829 is in fact 838.
