1 more than twice a number is 512

The number (x) in: "1 more than twice a number is 512" 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 1, you get 512.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 512

Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 1 = 512

2x + 1 - 1 = 512 - 1
2x = 511

2x/2 = 511/2
x = 255.5

Answer = 255.5

The answer above is correct, because twice 255.5 is 511, and 1 more than 511 is in fact 512.
