4 more than twice a number is 688

The number (x) in: "4 more than twice a number is 688" 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 688.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 688

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 = 688

2x + 4 - 4 = 688 - 4
2x = 684

2x/2 = 684/2
x = 342

Answer = 342

The answer above is correct, because twice 342 is 684, and 4 more than 684 is in fact 688.
