The number (x) in: "9 more than twice a number is 757" 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 757.
To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 757
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 = 757
2x + 9 - 9 = 757 - 9
2x = 748
2x/2 = 748/2
x = 374
Answer = 374
The answer above is correct, because twice 374 is 748, and 9 more than 748 is in fact 757.
