3 more than twice a number is 630

The number (x) in: "3 more than twice a number is 630" 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 630.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 630

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 = 630

2x + 3 - 3 = 630 - 3
2x = 627

2x/2 = 627/2
x = 313.5

Answer = 313.5

The answer above is correct, because twice 313.5 is 627, and 3 more than 627 is in fact 630.
