3 more than twice a number is 579

The number (x) in: "3 more than twice a number is 579" 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 579.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 579

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 = 579

2x + 3 - 3 = 579 - 3
2x = 576

2x/2 = 576/2
x = 288

Answer = 288

The answer above is correct, because twice 288 is 576, and 3 more than 576 is in fact 579.
