3 more than twice a number is 320

The number (x) in: "3 more than twice a number is 320" 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 320.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 320

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 = 320

2x + 3 - 3 = 320 - 3
2x = 317

2x/2 = 317/2
x = 158.5

Answer = 158.5

The answer above is correct, because twice 158.5 is 317, and 3 more than 317 is in fact 320.
