3 more than twice a number is 381

The number (x) in: "3 more than twice a number is 381" 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 381.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 381

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 = 381

2x + 3 - 3 = 381 - 3
2x = 378

2x/2 = 378/2
x = 189

Answer = 189

The answer above is correct, because twice 189 is 378, and 3 more than 378 is in fact 381.
