9 more than twice a number is 867

The number (x) in: "9 more than twice a number is 867" 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 867.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 867

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 = 867

2x + 9 - 9 = 867 - 9
2x = 858

2x/2 = 858/2
x = 429

Answer = 429

The answer above is correct, because twice 429 is 858, and 9 more than 858 is in fact 867.
