4 more than twice a number is 686

The number (x) in: "4 more than twice a number is 686" 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 686.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 686

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 = 686

2x + 4 - 4 = 686 - 4
2x = 682

2x/2 = 682/2
x = 341

Answer = 341

The answer above is correct, because twice 341 is 682, and 4 more than 682 is in fact 686.
