9 more than twice a number is 843

The number (x) in: "9 more than twice a number is 843" 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 843.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 843

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 = 843

2x + 9 - 9 = 843 - 9
2x = 834

2x/2 = 834/2
x = 417

Answer = 417

The answer above is correct, because twice 417 is 834, and 9 more than 834 is in fact 843.
