4 more than twice a number is 671

The number (x) in: "4 more than twice a number is 671" 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 671.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 671

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 = 671

2x + 4 - 4 = 671 - 4
2x = 667

2x/2 = 667/2
x = 333.5

Answer = 333.5

The answer above is correct, because twice 333.5 is 667, and 4 more than 667 is in fact 671.
