3 more than twice a number is 620

The number (x) in: "3 more than twice a number is 620" 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 620.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 620

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 = 620

2x + 3 - 3 = 620 - 3
2x = 617

2x/2 = 617/2
x = 308.5

Answer = 308.5

The answer above is correct, because twice 308.5 is 617, and 3 more than 617 is in fact 620.
