9 more than twice a number is 792

The number (x) in: "9 more than twice a number is 792" 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 792.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 792

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 = 792

2x + 9 - 9 = 792 - 9
2x = 783

2x/2 = 783/2
x = 391.5

Answer = 391.5

The answer above is correct, because twice 391.5 is 783, and 9 more than 783 is in fact 792.
