3 more than twice a number is 310

The number (x) in: "3 more than twice a number is 310" 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 310.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 310

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 = 310

2x + 3 - 3 = 310 - 3
2x = 307

2x/2 = 307/2
x = 153.5

Answer = 153.5

The answer above is correct, because twice 153.5 is 307, and 3 more than 307 is in fact 310.
