4 more than twice a number is 729

The number (x) in: "4 more than twice a number is 729" 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 729.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 729

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 = 729

2x + 4 - 4 = 729 - 4
2x = 725

2x/2 = 725/2
x = 362.5

Answer = 362.5

The answer above is correct, because twice 362.5 is 725, and 4 more than 725 is in fact 729.
