The number (x) in: "2 more than twice a number is 470" 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 470.
To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 470
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 = 470
2x + 2 - 2 = 470 - 2
2x = 468
2x/2 = 468/2
x = 234
Answer = 234
The answer above is correct, because twice 234 is 468, and 2 more than 468 is in fact 470.
