9 more than twice a number is 880

The number (x) in: "9 more than twice a number is 880" 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 880.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 880

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 = 880

2x + 9 - 9 = 880 - 9
2x = 871

2x/2 = 871/2
x = 435.5

Answer = 435.5

The answer above is correct, because twice 435.5 is 871, and 9 more than 871 is in fact 880.
