4 more than twice a number is 648

The number (x) in: "4 more than twice a number is 648" 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 4, you get 648.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 648

Then you solve the equation by subtracting 4 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 4 = 648

2x + 4 - 4 = 648 - 4
2x = 644

2x/2 = 644/2
x = 322

Answer = 322

The answer above is correct, because twice 322 is 644, and 4 more than 644 is in fact 648.
