3 more than twice a number is 315

The number (x) in: "3 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 3, you get 315.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 315

Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 3 = 315

2x + 3 - 3 = 315 - 3
2x = 312

2x/2 = 312/2
x = 156

Answer = 156

The answer above is correct, because twice 156 is 312, and 3 more than 312 is in fact 315.
