2 more than twice a number is 639

The number (x) in: "2 more than twice a number is 639" 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 639.

To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 639

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 = 639

2x + 2 - 2 = 639 - 2
2x = 637

2x/2 = 637/2
x = 318.5

Answer = 318.5

The answer above is correct, because twice 318.5 is 637, and 2 more than 637 is in fact 639.
