The number (x) in: "1 more than twice a number is 361" 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 1, you get 361.
To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 361
Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 1 = 361
2x + 1 - 1 = 361 - 1
2x = 360
2x/2 = 360/2
x = 180
Answer = 180
The answer above is correct, because twice 180 is 360, and 1 more than 360 is in fact 361.
