9 more than twice a number is 891

The number (x) in: "9 more than twice a number is 891" 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 891.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 891

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 = 891

2x + 9 - 9 = 891 - 9
2x = 882

2x/2 = 882/2
x = 441

Answer = 441

The answer above is correct, because twice 441 is 882, and 9 more than 882 is in fact 891.
