7 more than twice a number is 391

The number (x) in: "7 more than twice a number is 391" 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 7, you get 391.

To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 391

Then you solve the equation by subtracting 7 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 7 = 391

2x + 7 - 7 = 391 - 7
2x = 384

2x/2 = 384/2
x = 192

Answer = 192

The answer above is correct, because twice 192 is 384, and 7 more than 384 is in fact 391.
