3 more than twice a number is 321

The number (x) in: "3 more than twice a number is 321" 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 321.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 321

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 = 321

2x + 3 - 3 = 321 - 3
2x = 318

2x/2 = 318/2
x = 159

Answer = 159

The answer above is correct, because twice 159 is 318, and 3 more than 318 is in fact 321.
