The number (x) in: "2 more than twice a number is 905" 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 2, you get 905.
To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 905
Then you solve the equation by subtracting 2 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 2 = 905
2x + 2 - 2 = 905 - 2
2x = 903
2x/2 = 903/2
x = 451.5
Answer = 451.5
The answer above is correct, because twice 451.5 is 903, and 2 more than 903 is in fact 905.
