2 more than twice a number is 644

The number (x) in: "2 more than twice a number is 644" 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 644.

To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 644

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 = 644

2x + 2 - 2 = 644 - 2
2x = 642

2x/2 = 642/2
x = 321

Answer = 321

The answer above is correct, because twice 321 is 642, and 2 more than 642 is in fact 644.
