9 more than twice a number is 863

The number (x) in: "9 more than twice a number is 863" 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 863.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 863

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 = 863

2x + 9 - 9 = 863 - 9
2x = 854

2x/2 = 854/2
x = 427

Answer = 427

The answer above is correct, because twice 427 is 854, and 9 more than 854 is in fact 863.
