4 more than twice a number is 691

The number (x) in: "4 more than twice a number is 691" 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 691.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 691

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 = 691

2x + 4 - 4 = 691 - 4
2x = 687

2x/2 = 687/2
x = 343.5

Answer = 343.5

The answer above is correct, because twice 343.5 is 687, and 4 more than 687 is in fact 691.
