1 more than twice a number is 315

The number (x) in: "1 more than twice a number is 315" 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 1, you get 315.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 315

Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 1 = 315

2x + 1 - 1 = 315 - 1
2x = 314

2x/2 = 314/2
x = 157

Answer = 157

The answer above is correct, because twice 157 is 314, and 1 more than 314 is in fact 315.
