The number (x) in: "2 more than twice a number is 849" 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 2, you get 849.
To solve this, you first write the problem as an algebra equation as follows: 2x + 2 = 849
Then you solve the equation by subtracting 2 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 2 = 849
2x + 2 - 2 = 849 - 2
2x = 847
2x/2 = 847/2
x = 423.5
Answer = 423.5
The answer above is correct, because twice 423.5 is 847, and 2 more than 847 is in fact 849.
