7 more than twice a number is 309

The number (x) in: "7 more than twice a number is 309" 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 309.

To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 309

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 = 309

2x + 7 - 7 = 309 - 7
2x = 302

2x/2 = 302/2
x = 151

Answer = 151

The answer above is correct, because twice 151 is 302, and 7 more than 302 is in fact 309.
