9 more than twice a number is 854

The number (x) in: "9 more than twice a number is 854" 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 854.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 854

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 = 854

2x + 9 - 9 = 854 - 9
2x = 845

2x/2 = 845/2
x = 422.5

Answer = 422.5

The answer above is correct, because twice 422.5 is 845, and 9 more than 845 is in fact 854.
