The number (x) in: "9 more than twice a number is 969" 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 9, you get 969.
To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 969
Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 9 = 969
2x + 9 - 9 = 969 - 9
2x = 960
2x/2 = 960/2
x = 480
Answer = 480
The answer above is correct, because twice 480 is 960, and 9 more than 960 is in fact 969.
