9 more than twice a number is 869

The number (x) in: "9 more than twice a number is 869" 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 869.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 869

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 = 869

2x + 9 - 9 = 869 - 9
2x = 860

2x/2 = 860/2
x = 430

Answer = 430

The answer above is correct, because twice 430 is 860, and 9 more than 860 is in fact 869.
