The number (x) in: "2 more than twice a number is 351" 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 351.
To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 351
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 = 351
2x + 2 - 2 = 351 - 2
2x = 349
2x/2 = 349/2
x = 174.5
Answer = 174.5
The answer above is correct, because twice 174.5 is 349, and 2 more than 349 is in fact 351.
