4 more than twice a number is 669

The number (x) in: "4 more than twice a number is 669" 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 669.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 669

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 = 669

2x + 4 - 4 = 669 - 4
2x = 665

2x/2 = 665/2
x = 332.5

Answer = 332.5

The answer above is correct, because twice 332.5 is 665, and 4 more than 665 is in fact 669.
