9 more than twice a number is 849

The number (x) in: "9 more than twice a number is 849" 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 849.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 849

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 = 849

2x + 9 - 9 = 849 - 9
2x = 840

2x/2 = 840/2
x = 420

Answer = 420

The answer above is correct, because twice 420 is 840, and 9 more than 840 is in fact 849.
