3 more than twice a number is 717

The number (x) in: "3 more than twice a number is 717" 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 717.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 717

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 = 717

2x + 3 - 3 = 717 - 3
2x = 714

2x/2 = 714/2
x = 357

Answer = 357

The answer above is correct, because twice 357 is 714, and 3 more than 714 is in fact 717.
