3 more than twice a number is 311

The number (x) in: "3 more than twice a number is 311" 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 311.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 311

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 = 311

2x + 3 - 3 = 311 - 3
2x = 308

2x/2 = 308/2
x = 154

Answer = 154

The answer above is correct, because twice 154 is 308, and 3 more than 308 is in fact 311.
