The number (x) in: "5 more than twice a number is 911" 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 5, you get 911.
To solve this, you first write the problem as an algebra equation as follows: 2x + 5 = 911
Then you solve the equation by subtracting 5 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 5 = 911
2x + 5 - 5 = 911 - 5
2x = 906
2x/2 = 906/2
x = 453
Answer = 453
The answer above is correct, because twice 453 is 906, and 5 more than 906 is in fact 911.
