9 more than twice a number is 855

The number (x) in: "9 more than twice a number is 855" 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 855.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 855

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 = 855

2x + 9 - 9 = 855 - 9
2x = 846

2x/2 = 846/2
x = 423

Answer = 423

The answer above is correct, because twice 423 is 846, and 9 more than 846 is in fact 855.
