9 more than twice a number is 808

The number (x) in: "9 more than twice a number is 808" 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 808.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 808

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 = 808

2x + 9 - 9 = 808 - 9
2x = 799

2x/2 = 799/2
x = 399.5

Answer = 399.5

The answer above is correct, because twice 399.5 is 799, and 9 more than 799 is in fact 808.
